Attenuated Total Reflectance Absorption Spectroscopy

Posted on: November 19th, 2021

Absorption spectroscopy is a powerful technique used to identify and quantify a wide range of analytes since the absorption bands directly correlate to electronic or vibrational energy level transitions. Most molecular vibrations tend to have very low transition energies between 0.05 and 0.5eV, corresponding to wavelengths from 2.5 mm to 25 mm. While low energy,…
