The relaxation rams of u = 3 and u = 4 were determined to be k\* = (2.8 i-0.4) X IO-" cm3 molecule-t SC' and k$ = (7.2 + 05) X lo-" cm3 molecule-t SC' at 293 K. It is shown that single quantum energy transfer can account for all of rhe nirational relaxation.
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
