A soleil-babinet compensator based Raman optical activity spectrometer: interpretation of roa couplets in (+)-(3R)-methylcyclohexanone

The Raman optical activity (ROA) spectrum of (+)-(3R)-methylcyclohexanone from 150 to 1400 cm −1 measured using a novel ROA spectrometer is reported. The spectrometer features a Soleil-Babinet compensator to produce high-quality circularly polarized laser radiation. The principal ROA couplets are assigned and interpreted in terms of pairs of coupled vibrational motions.
