Vibrational energy relaxation and vibrational cooling of polyatomic liquids were studied with the ultrafast infrared-Raman (IR-Raman) technique. In the IR-Raman technique, a type of two-dimensional vibrational spectroscopy, a vibrational transition is pumped with a mid-infrared pulse and the instant

The energy rekstion of the lowest vibrational Ieke (U = 1) of liquid oxygen in the electronic ground state aas investigated \Cthin a wide temperature range (53.4 Ii < T < 96 R). The relaation time exhibits a peak vlllue of; = 3.1 ms around 65 I< and is shorter at loxcer and higher temperatures. The
