Abstract

The difference in specular reflection of left and right circularly polarized light from a naturally optically active sample (an absorbing chiral liquid) was observed and measured as a function of wavenumber under conditions of double-pass total reflection. The imaginary part of the refractive index reached a maximum value on the order of 10^-4 (at 21,000 cm^-1); the real and imaginary parts of the complex gyrotropic parameter were on the order of 10^-8 and 5 X 10^-7, respectively. In accord with recent predictions, the observed differential circular reflection exceeded the intrinsic chiral parameters by some three orders of magnitude. This is the first observation of natural molecular optical activity by coherent light scattering.
