Dual circular polarization Raman optical activity of related terpene molecules: Comparison of backscattering DCPI and right‐angle ICP spectra

The backscattering in‐phase dual circular polarization (DCP I ) Raman and Raman optical activity (ROA) for a series of terpene molecules is reported. The selected molecules were studied in three groups of closely related structures and correlations between ROA features and structural elements among molecules within these groups are discussed. One aim of this study was to uncover additional details regarding the sensitivity of ROA to stereostructural features in molecules and to elucidate further the degree of local character of this new stereochemical probe. Another was to compare the backscattering DCP I ROA intensities reported here with those obtained using depolarized right‐angle incident circularly polarized (ICP) ROA for some of the same molecules more than a decade ago.
