Abstract
The excitation of optical isomers to the electronic vibrational state S 1 by high-intensity circularly polarized laser UV light results in a significant growth (by more than two orders of magnitude) of the anisotropy factor in asymmetric photolysis. It has been demonstrated for two types of biomolecules, namely, DL-tyrosine amino acid in aqueous solution and provitamin D 3 (7-dehydrocholesterol) in ethanol solution, that the anisotropy factor increased from 8.8×10 −5 and 1.5 × 10 −4 to 2.4 × 10 −2 and 4.4 × 10 −2, respectively.
