Abstract:

This paper studies theoretically the effect of circularly polarized laser on ESR spectra in a spin specie system. The antisymmetric polarizability and the laser-induced ESR shift (Δv -- Δv+) of the complex [IrBr6]2- were calculated. The influence of the width г of the absorption line on the ESR shift was discussed. The results show that the ESR shift can be as large as 1MHz order of magnitude at a frequency near optical absorption, which is similar to that of the sodium atom.

Key words: Antisymmetric polarizability, Laser-induced ESR shift, Transition metal complex [IrBr6]2-
