|dc.description.abstract||Recently the theory of optical activity was extended to predict and describe and intensity differential betweeen right- and left-handed circularly polarized light undergoing Raman scattering by chiral molecules. The resulting circular differential Raman (CDR) spectra provide a new, unexplored chiroptical technique that could be more useful than electronic circular dichroism since CDR is not limited to examination of accessible UV chromophores. Indeed, the entire molecule, including substituent groups as well as the molecular framework itself, is directly amenable to chiroptical study. We have succeeded in observing the CDR spectra of several optically active compounds by excitation with electro-optically modulated 632.8 nm He-Ne laser radiation producing ca. 70 mW at the sample. Observation of both the first and second harmonic components along with the de component of the modulated signal allowed the normalized CDR spectra to be obtained. A description of the experiment and some of our results with several small alicyclics, alcohols, amines, and alkyl halides will be presented.||en_US|
