Ro?arional relaxarion umes have btcn m-red for methane (13CD.,) in collisions with i&elf, He, Ne. Ar, Kr. Xc, and CH,F,. using the method of infrared double resonance Collision efficiencies range from one-half to greater than -kinetic, and the measured relaxation UIIIS are longer in the vibrational ground state Lhan in Lhe u_, = 1 excited spate
