Fifth-order Raman spectroscopy of liquid benzene: Experiment and theory

The passive-phase stabilization of diffractive optics was exploited to characterize the heterodyned fifth-order Raman response stabilization of diffractive optics. The overall response characteristics such as a complete lack of signal along the pump delay, an elongated signal along the probe delay, and a short-lived signal along the time diagonal are similar to those of liquid carbon disulfide, but the observed change in phase between the nuclear and electronic response along the probe delay and diagonal is unique, as it is not present in carbon disulphide.
