NEW APPROACH TO THE THEORY OF CIRCULAR-DICHROISM

Using the semiclassical approach for the description of the propagatio n of the electromagnetic waves in optically active isotropic media we derive a new formula for the circular dichroism parameter. The theory is based on the idea of the time damped electromagnetic wave interacti ng with the molecules of the sample. In this theory, the Lambert-Beer law need not be taken as an empirical law, however, it follows natural ly from the requirement that the electromagnetic wave obeys the Maxwel l equations.
