DISYMMETRY INDEXES BASED ON OPTICAL ROTATIONAL POLARIZABILITY OF CHIRAL MOLECULES

New molecular disymmetry indices are suggested based on an analysis of the moments of rotational polarizability defining optical activity. I t is shown that the fourth moment of rotational polarizability coincid es with the electron-kinematic index of chirality, introduced previous ly by one of the authors. The norm of imaginary frequency rotational p olarizability is suggested for use as an additional disymmetry index. Illustrative Hartree-Fock calculations of these chirality indices with the 6-31G basis set are performed for hydrogen peroxide, water trimer , and some amino acids.
