The vibrational relaxation time of liquid Ccl4 was meas- ured as a function of temperature in a Brillouin-scattering experiment. Between -5OC and 65OC the relaxation time ~~~~ decreases from 160 psec to 145 psec. The nonrelaxing fraction of the bulk viscosity was found to be 1.5 to 2.5 times the she

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
The proton spin-spin rebxation time for liquid chloroform has been measured over the temperature range -54" to +9O"C. The values of Ta(H) decrease with increasing temperature contrary to the behavior obsemed for Tr (H). Values of Tz (I-l) calculated from experimental values of Tr (H) and Tz(Cl) repr
