STIMULATED LOW-FREQUENCY EMISSION FROM ANISOTROPIC MOLECULES IN MICRODROPLETS

Spectral broadening of the input-laser line and the stimulated Raman l ine have been observed in microdroplets of carbon disulfide, benzyl al cohol, toluene, chloroform and a binary mixture of carbon disulfide in ethanol. The broadening is asymmetrical and extends more than 500 cm- 1 towards the low-frequency side of the input-laser line and the stimu lated Raman lines. The broadening is proposed to arise from multiple-o rder stimulated low-frequency scattering associated with librational a nd dipole-induced-dipole translational motions.
