Linear polarization Raman optical activity: a new form of natural optical activity

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 the product of the transition-polarizability and optical-activity tensors. This is the first form of ROA to be identified that does not directly involve the use or measurement of circularly polarized radiation.
