What is another name for electronic spectroscopy?

Electronic Spectroscopy: Overview

Electronic Spectroscopy, also widely known as UV/VIS Spectroscopy, is a fundamental technique in physical and analytical chemistry, providing detailed information about the electronic structure of molecules. This technique involves the absorption of ultraviolet (UV) or visible (VIS) light by atoms or molecules, leading to electronic transitions from lower to higher energy states. The spectrum obtained represents the wavelength and intensity of absorption, offering insights into the molecular structure, concentration, and chemical bonding.

Principles of UV/VIS Spectroscopy

At the heart of electronic spectroscopy is the interaction between light and matter. When molecules absorb UV or visible light, electrons in the molecule are excited from their ground state to higher electronic states. The specific wavelengths at which absorption occurs depend on the molecular structure, including aspects like conjugated systems, which can lower the energy required for these transitions. The resulting spectra can be used to characterize substances and determine their concentration in a solution.


Electronic spectroscopy has a broad range of applications, from the analysis of organic compounds, biomolecules, and polymers to environmental monitoring and food safety. It is a powerful tool for understanding the electronic properties of materials and is instrumental in studies of molecular dynamics, chemical kinetics, and reaction mechanisms.


In summary, electronic spectroscopy, or UV/VIS Spectroscopy, is an indispensable technique in the chemical sciences. It provides a window into the molecular world, allowing scientists to decipher the structure and behavior of molecules through their electronic spectra.
