Raman Spectroscopy - Chemistry

Raman Spectroscopy Raman Spectroscopy has become an incredibly useful analytical technique for the identification of organic, inorganic, and biological samples. Raman spectra can generally be measured from solids, liquids, and gases, including thin films and powders.

Microplastics Identification FTIR Raman Guide

Analysis of particles from 100 microns to 1 micron Once the particle size falls much below 100 microns, some magnification is required. There are two options here; IR microscopy and Raman microscopy (both techniques are also referred to as microspectroscopy). For particles less than 10 microns in size, Raman microscopy is the preferred choice.

Raman and mid-IR spectroscopy are complementary techniques and usually both are required to completely measure the vibrational modes of a molecule. Although some vibra-tions may be active in both Raman and IR, these two forms of spectroscopy arise from different processes and different selection rules. In general, Raman spectroscopy is best at
