A Raman spectrometer’s spectral resolution is determined by its spectral dispersion in conjunction with the entrance slit width. We explain the instrument design parameters involved.

Spectral Resolution and Dispersion in Raman Spectroscopy

An ongoing challenge within the forensic science community is the development of consistent report and testimony language that conveys results in a meaningful manner.

A Raman study of vitamin C, also known as ascorbic acid, is conducted at high pressure to determine phase changes and crystal symmetry through spectral interpretation.

The Effect of High Pressure on Ascorbic Acid Structure

Raman measurements can be used to infer the temperature of a material based on the Stokes and anti-Stokes band signal strengths, and by applying a predefined mathematical relationship. In reality, the temperature, Raman shift, and laser excitation wavelength all interact, and should be considered to better understand these measurements.

A famous and admired professor of analytical chemistry, Gary M. Hieftje, is officially retiring. He has been a prominent faculty member at Indiana University for 50 years, and a beloved mentor, colleague, and friend to many. In this special feature, we take a look at his many contributions, and his broad impact on the field.

The spectral behavior of water is studied using Raman with an NIR spectrograph and dual wavelength lasers for measurements of both the fingerprint and the OH stretching regions. Raman spectra are recorded between 5 ⁰C and 80 ⁰C, and treated with both band-fitting and the 2D-COS algorithm revealing improved insights into the spectral behavior of water.
