Stress, Strain, and Raman Spectroscopy

September 01, 2019

Molecular Spectroscopy Workbench

When stress is applied to an object, it can produce strain. Strain can be detected through changes in peak position and bandwidth in Raman spectra. Here, we show examples of how strain in technologically important materials appears in the Raman spectra.
