Produced in Partnership with Avantes BVReviewed by Maria OsipovaAug 15 2024
In this article, Avantes discusses the differences and alignments between Raman and infrared spectroscopy for unknown material identification and reaction monitoring. While both techniques are similar when it comes to measuring a material's vibrational energy levels, the selection rules governing them diverge somewhat.
This article uses molecular symmetries and group theory to comprehensively analyze which vibrational modes are best suited for Raman analysis and which ones are appropriate for infrared. The sample discussed in this article is Octasulfur, the most abundant sulfur in nature.
