Raman Thermometry

Raman spectroscopy can be used to determine the temperature of a material when other more direct means are either impractical or not possible. The material’s temperature can affect the peak position of Raman bands. When a Raman band shifts significantly with temperature, the monitoring of the peak position can be the most straightforward manner of determining temperature provided the Raman spectrometer has sufficient spectral resolution. Another method is to determine the temperature from the ratio of the Stokes and anti-Stokes signal strengths of a given Raman band. The latter method requires the ability to detect light at wavelengths longer and shorter than that of the laser and an accurate measurement of the wavelength-dependent instrument response function.

How has spectroscopy education evolved over the years?
FT-IR spectroscopy, long treated as a mature bench technique for confirming a carbonyl stretch or fingerprinting a polymer, has quietly become one of chemistry’s most versatile discovery engines: it now infers molecular structure straight from a spectrum without a reference library, resolves chemistry tens of nanometers wide, and screens a fingerstick of blood for disease in minutes. The last five years of published research show FT-IR moving from a confirmatory tool into a predictive, autonomous, and field-ready analytical platform.
In this panel discussion, five SpecAcademy instructors examined why spectroscopy expertise has declined and how SpecAcademy aims to rebuild it through curated, fundamentals-based education suited to increasingly complex analytical work.

The agreement gives North American customers a stocked, domestic source for InGaAs PIN photodiodes and avalanche photodiodes from the Scottish manufacturer.
The gap between classroom training and industry practice is pushing analysts toward familiar techniques instead of the most appropriate ones.
Panelists from the Society for Applied Spectroscopy, the Coblentz Society, Syensqo, Specac, and the University of Georgia discuss how a mismatch between academic curricula and industry practice leaves many analysts unsure when, and how, to use infrared and Raman spectroscopy.
