Abstract
We calculate the vibrational energy relaxation rate constants for oxygen mo lecules in oxygen/argon liquid mixtures of various mole fractions at 77 K. Our results are uniformly about a factor of 5 larger than experimental valu es, which are in the range of 100 s(-1). When the mole fraction-dependent r esults are scaled by their values for neat oxygen, theory and experiment ar e in excellent agreement. (C) 1999 American Institute of Physics.
