The vibrational relaxation times for F$sub 2$ in Ar and He and for H$sub 2$ and D$sub 2$ in He are calculated and compared with the data from shock tube experiments. The near-adiabatic approximation developed previously was employed to calculate the relaxation times. A comparison of these results with those from the SSH theory, which contain a ''static'' approximation, shows the current theory to be as accurate or more accurate than the SSH theory except for the systems dominated by impulsive collisions. Calculations treating transitions in addition to the 1 to 0 transition were also performed and discussed. (AIP)
