An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. [1]

Optical spectroscopy, also known as UV-Vis spectroscopy, is a versatile, non-invasive technique. Using optical spectroscopy, researchers can explore the properties of different samples and materials by analyzing how they interact with light.

In spectroscopy, we use light to determine a tremendous range of molecular properties, including electronic, vibrational, rotational, and electron and nuclear spin states and energies.

2025年1月25日 · Optical spectroscopy is used routinely to identify the chemical composition of matter and to determine its physical structure.

2023年8月29日 · Know the 5 components necessary for building optical instruments for absorption and emission studies. Know the differences between continuum and line sources. Be able to give examples of each. For blackbody radiation sources, be able to calculate the wavelength maximum at different temperatures.

two-dimensional electronic and vibrational spectroscopy; This revised and updated edition provides expanded discussions of laser spectroscopy, crystal symmetry, birefringence, non-linear optics, solar cells and light-emitting diodes.

8.1: Optical Atomic Spectra The energy of ultraviolet and visible electromagnetic radiation is sufficient to cause a change in an atom’s valence electron configuration, resulting atomic absorption, atomic emission, and atomic fluorescence spectra.

Spectroscopy is a general methodology that can be adapted in many ways to extract the information you need (energies of electronic, vibrational, rotational states, structure and symmetry of molecules, dynamic information). Understand how light interacts with matter and how you can use this to quantitatively understand your sample.

Optical emission spectroscopy (OES) is a technique where a sample is heated to a high temperature where electrons in the sample are excited to a high energy state. As the sample cools, the electrons relax and emit radiation in the visible region of the spectrum (OES).

In this book we will discuss the essential features of optical spectroscopy with minimum descriptions of complex theories, various spectrophotometric proce- dures and apparatus.
