We report the first isolation of preresonance Raman scattering behavior in Raman optical activity (ROA) and the first measurement of out-of-phase dual circular polarization (DCPu) ROA. Using a series of molecules of increasing delocalized electronic structure, we observe a correlated increase in the

β¦ Synopsis
The theoretical description of dual circular polarization (DCP) Raman optical activity is presented. It is shown that for forward scattering, right-angle scattering and backward scattering, it is possible to measure a form of ROA in which both the incident and scattered circular polarizations are simultaneously switched between right and left circular states. DCP ROA is shown to be equal to either the sum or difference of the corresponding incident and scattered circular polarization ROA intensities for nearly the same parent Raman intensity.

The first measurements of scattered circular polarization (SCP) Raman optical activity (ROA) are reported in which the degree of circular polarization of the scattered light is determined. The SCP ROA spectra are relatively simple to measure and confirm theoretical predictions of their relation to i
A new form of natural optical activity is identified on the basis of a general theory of natural Raman optical activity (ROA). This novel ROA phenomenon is predicted to occur as the difference in Raman-scattered intensity for pairs of linearly polarized measurements and depends on the real part of t
