Abstract

A complete theory of natural Raman optical activity (ROA) covering all forms of ROA, ICP, SCP and DCP (dual circular polarization), as a function of scattering angle and incident or scattering polarizer angle, has been recently developed in our laboratory.1 We use the results of this theory to predict differences in ICP and SCP ROA experiments. In the cases of (+)-trans-pinane and (-)-$\alpha$-pinene, we have measured depolarized ICP and SCP and ROA for $90^{\circ}$ scattering angle and find no difference in ROA intensity to within experimental error. Theoretical justification of this result and predictions of where differences between ICP and SCP ROA are expected to occur will be discussed
