Temporally two-dimensional femtosecond spectroscopy of binary mixture of CS2

Abstract
We have studied the inhomogeneity of the low-frequency modes of binary mixtures of CS2 with various cosolvents by the temporally two-dimensional spectroscopy with femtosecond pulses. The inhomogeneity in the underdamped mode is found to be decreased upon dilution for all the solvents investigated.
