Analytical Chemistry is the study of the method used to separate, identify and quantify matter with the help of instruments. The separation, identification or quantification will constitute of the entire analysis or it will be combined with another method. The separation will isolate analytes. Quantitative analysis specifies the numerical amount or concentration and qualitative analysis identifies the analytes. Analytical chemistry consists of different methods such as classical, wet chemical methods and modern, instrumental methods. These classical qualitative methods use separations process like precipitation, extraction, distillation, etc. Identification of the chemical may be based on the color of it, odor, melting point, boiling point, reactivity, and radioactivity. Quantitative analysis uses mass or volume changes to quantify the amount.

When a molecule or crystal scatters light, most photons which are scattered are elastically scattered. These photons maintain the same energy (frequency) and, hence, wavelength, as the incident photons. Though, a small fraction of light (nearly 1 in 107 photons) is scattered at optical frequencies different from, and usually lower than the frequency of the incident photons. The process which leads this inelastic scatted is Raman Effect. The Raman scattering can happen with a change in rotational, electronic or vibrational energy of a molecule. If the scattering is elastic, the process is known as Rayleigh scattering. If it’s not elastic, the process is called Raman scattering. 

In this, spectroscopy tools are used to derive many properties of stars and galaxies, such as their composition and movement. This study is based on using different spectroscopy techniques to measure the spectrum of electromagnetic radiation, including the visible radio and light which radiates from stars and other celestial objects. Many properties such as temperature, density, mass, distance, chemical composition, and relative motion can be revealed by a stellar spectrum using Doppler shift measurements. Astronomical Spectroscopy can also provide us with the physical properties of many other celestial objects such as planets, galaxies, nebulae, and active galactic nuclei.

One of the most widely and commonly used spectroscopic techniques is Infrared Spectroscopy. The absorbing groups in the infrared region absorb within a certain wavelength region. When this absorption is compared with other regions like ultraviolet and other visible regions the absorption peaks are usually sharper in Infrared Spectroscopy. By this, we can say the Infrared (IR) Spectroscopy is very sensitive to determine the functional groups within the sample with different functional group absorb a different particular frequency of IR radiation. Every molecule, characteristic spectrum often referred to as the fingerprint, it can identify by comparing its absorption peak with the data bank of spectra. Infrared Spectroscopy is playing a vital role in the identification and structural analysis of different types of substances, of both organic and inorganic compounds and also used in the qualitative and quantitative analysis of complex mixtures of similar compounds.

The method of elemental analysis which exploits the properties of atoms while excited by external energy in the form of electromagnetic radiation or photons with fine frequencies is known as Atomic Spectroscopy. The basic principle of atomic absorption spectrometry is capacity of atoms to absorb energy from photons with specific frequencies. These measurements rely on the determination of the quantity of light at the resonance wavelength is absorbed when it comes to a group of atoms. By providing a sample with sufficient thermal energy to dissociate the chemical compounds into the free states of atoms we can obtain the atomic vapor required.

It is the study which involves the interaction of UV Visible radiation with molecules. UV will have the right amount of energy to cause an electronic transition of an electron from one filled orbital to another of greater energy unfilled orbital. The result when UV interacts with a molecule at the appropriate wavelength the electron is promoted to greater energy molecular orbital, and then the molecule is in an excited state. We get the information on the energy gap which is related to the functional group.

The study which focusses on fluorescence, phosphorescence, and chemiluminescence of chemical systems techniques is Luminescence Spectroscopy. Light emissions produced by irradiation with light and occur within nanoseconds to milliseconds after irradiation is Fluorescence spectroscopy. Light emissions which occur up to hours after irradiation is known as Phosphorescence Spectroscopy. It stores energy in metastable states and released through the slow and thermal process. This phenomenon was discovered early on for phosphorous. The Chemiluminescence is the process which occurs when the light emitted during cold chemical reactions.

KeV photons are X-rays. Atomic X-rays are produced throughout electronic transitions to the inner shell states in atoms of the uncertain atomic number. They produce distinctive energies related to an atomic number, which in the result where each element has a characteristic X-ray Spectrum. The elemental composition of the sample will produce qualitative results through analysis of X-ray emission. The wavelength of X-Rays is approximately 10nm to 0.001nm. The Gamma rays are released by the nuclear processes; X-rays are emitted when fast electrons collide with matter. Technically, X-rays are produced by means of an X-ray tube, a simple form of a linear particle accelerator.

The technique used in combination on scanning electron microscopy (SEM) through chemical microanalysis is Energy Dispersive X-Ray Spectroscopy (EDS or EDX). The X-ray emitted by this technique from the sample during the shelling of an electron beam to provide the elemental composition of analyzed volume.  The unique feature is that it can analyze up to 1 µm or less can be analyzed. The sample is shelled by the SEM’s electron beam, where electrons are ejected from these atoms comprising the sample’s surface. The result of the electron vacancies are filled by electrons from a higher state, and an x-ray is emitted to for the stability of energy difference between the electrons.

The spectroscopy technique which allows monitoring the evolution of light spectrum in time is known as Time-resolved (TR) Spectroscopy. In this way, we can observe the time-based behavior of different optical phenomena such as fluorescence or non-linear effects. This technique will be applied to any procedure which leads to change in properties of a material and with the help of pulsated lasers; we can probably study the processes which occur on time scale as small as 10-16 seconds.

Nuclear Magnetic Resonance (NMR) is a spectroscopy method which depends on the absorption of electromagnetic radiation by nuclei of the molecules. Proton Nuclear magnetic resonance spectroscopy is a standout amongst the most instruments for clarifying the quantity of hydrogen or proton in the compound. It is utilized to contemplate a wide assortment of nuclei. The principle behind NMR is that the nuclei have spin and they are electrically charged. In the event that an external attractive field is connected, an energy exchange is conceivable between the base energy to a higher energy level (for the most part a single energy hole). The energy exchange happens at a wavelength that compares to radio frequencies and when the turn comes back to its base level, energy is transmitted at a similar recurrence. The standard that matches this transfer is estimated from multiple ways of view and prepared to yield an NMR range for the nucleus concerned.
