types of spectroscopy slideshare

is a particular type of infrared spectroscopy. 0 From Embeds. • When radiation meets matter, the radiation is either scattered, emitted or absorbed • so they are of three types 1.absorption spectroscopy 2.scattering spectroscopy 3.emission spectroscopy Abstract. Electronic structure research with various spectroscopes. The absorption or emission energies are characteristic of the specific atom and small energy variations may occur that are characteristic of particular chemical bonding. 22 Types of Spectroscopy with Definition, Principle, Steps, Uses; Nuclear Magnetic Resonance (NMR) Spectroscopy; Infrared (IR) Spectroscopy; Gamma-ray (γ-ray) Spectroscopy; Southern Blot- Principle, Steps and Applications; Radial Immunodiffusion- Objectives, Principle, Procedure, Results, Applications, Advantages… PMT Xenon Source … The orange area is an approximation for the integral over the full spectrum. Named series of lines include the principal, sharp, diffuse and fundamental series. For instance, blackbody radiation is due to the thermal motions of atoms and molecules within a material. X-Ray Spectroscopy- Principle, Instrumentation and Applications X-rays make up X-radiation, a form of electromagnetic radiation. A commonly encountered molecular spectrum is that of nitrogen dioxide.

Emission Spectroscopy: • An analytical technique in which emission (of a particle or radiation) is … Inks, dyes and paints include chemical compounds selected for their spectral characteristics in order to generate specific colors and hues. On SlideShare. Atomic spectroscopy was the first application of spectroscopy developed. [1][2][3][4][5][6] In simpler terms, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum; indeed, historically, spectroscopy originated as the study of the wavelength dependence of the absorption by gas phase matter of visible light dispersed by a prism. Types of spectroscopy 17. X-rays of sufficient energy are used to excite the inner shell electrons in the atoms of a sample. Types of Spectroscopy: Acoustic resonance; Time-resolved; Photoemission; X-ray photoelectron; Circular Dichroism; IR Spectroscopy (Infrared spectroscopy) Raman spectroscopy Instead, FT -IR uses an interferometer to produce an IR spectrum. Spectroscopy is the study of the interaction between matter and electromagnetic radiation as a function of the wavelength or frequency of the radiation. The types of radiative energy studied include: The types of spectroscopy also can be distinguished by the nature of the interaction between the energy and the material. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Back in the late 1960s we used dispersive technologies, where a grating or prism would disperse the light into the wavelengths we wanted.

This type of spectroscopy is used for the quantification of biological samples either directly or via colorimetric assays. Absorption Spectroscopy:• An analytical technique which concerns with the measurement of absorption of electromagnetic radiation.• e.g. = After inventing the spectroscope, Robert Bunsen and Gustav Kirchhoff discovered new elements by observing their emission spectra. Introduction • Technique is also known as OPTICAL EMISSION SPECTROSCOPY (OES) • The study of radiation emitted by excited atoms and monatomic ions • Relaxation of atoms in the excited state results in emission of light • Produces line spectra in the UV-VIS and the vacuum UV regions The types of spectroscopy are distinguished by the type of radiative energy involved in the interaction. Nuclei also have distinct energy states that are widely separated and lead to gamma ray spectra. In some cases spectral lines are well separated and distinguishable, but spectral lines can also overlap and appear to be a single transition if the density of energy states is high enough. Downloads. As a result, these spectra can be used to detect, identify and quantify information about the atoms and molecules. 1.3.3 Di erent types … See our Privacy Policy and User Agreement for details. In Chemistry, Spectroscopy helps to study or analyse various chemical compounds or elements, whereas, in Physics, it helps to determine the makeup of the atmospheres of planets.

Reading: Vibrational Spectroscopy Revised: 2/24/15 The most widely used vibrational spectroscopy is Infrared (IR) spectroscopy. 33 Actions. Fluorimetry is a type of spectroscopy which measures the emitted radiation from a substance. Studies in molecular spectroscopy led to the development of the first maser and contributed to the subsequent development of the laser. 0 Number of Embeds. Continuous analyzers: These analyzers are similar to a filter or monochromator used for optical spectroscopy. Atomic absorption lines are observed in the solar spectrum and referred to as Fraunhofer lines after their discoverer. E. B. Wilson, J. C. Decius, and P. C.
