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.

Raman Laser Sources Explained: Wavelengths, Types, and How to Choose

Raman laser sources determine signal strength, fluorescence interference, spatial resolution, and sample damage in Raman spectroscopy. This guide explains the different types of Raman lasers, common wavelengths, and how to choose the right laser for your experiment.

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
