✦ Synopsis

Here, reflt'x'ted shock temperatures were calcu-lal~ by assuming that tmndational, rotational and vii~rational freedoms of all species were completely relaxed. However, vibrational relaxation of nitrogen is comparable to the induction peric, d in the present experimental conditions -~. Another calculation by using temperatures corresponding to frozen vibration of nitrogen was al~ performed. These relationships are expressed by the least-squaru~ equations ! and 2. log z[O,] = ;11.30 ~ 0.03) x 10aiT}.
