Setup Of A Spectrometer To Detect Raman Optical Activity — •Klaus Hofmann — Universität Würzburg, Institut für Physikalische und Theoretische Chemie

A custom-built Raman spectrometer was modified to detect Raman optical activity (ROA), a type of vibrational circular dichroism. A modulation scheme was implemented to repeatedly convert linear to right and left circular polarized light for excitation. Python was used to automate the experiment, data acquisition and post-processing. Experimental challenges and their influences on the resulting ROA signal as well as the margins of error are presented. The recorded ROA spectrum of (-)-α-pinene was acquired by subtracting the spectra of both enantiomers and shows good agreement with literature.
