Raman Selection Rules
Raman selection rules determine which molecular vibrations are Raman active. Learn the polarizability requirement, the mutual exclusion rule, and how symmetry governs what you see in a Raman spectrum.

Polarizability in Molecules and Materials
Polarizability describes how easily the electron cloud of an atom, molecule, or solid can be distorted by an electric field. It plays a central role in Raman spectroscopy, dielectric behaviour, and electron spectroscopies such as Auger and XPS.
Basic Principles of Raman Spectroscopy
Raman spectroscopy is based on the inelastic scattering of light caused by molecular vibrations. This guide explains the fundamental principles behind Raman spectroscopy, including Raman scattering, vibrational energy levels, and how Raman spectra are generated
