This paper explores the differences and similarities between Raman and infrared spectroscopy in regard to unknown material identification and reaction monitoring. While these techniques share commonalities in terms of measuring material vibrational energy levels, the selection rules overseeing them are fairly different.
The article offers a complex analysis of which vibrational modes are more well-suited for Raman analysis and which are more appropriate for infrared, using group theory and molecular symmetries. The sample seen in this article is Octasulfur, the most typically present sulfur in nature.
