摘要：

Rate constants for the removal of O-2(b(1)Sigma(+)(g)) by collisions with I-2 and NO have been determined over the temperature range from 300 to 750 K. Time dependent laser induced fluorescence (LIF) from the b(1)Sigma(+)(g) -> X-3 Sigma(-)(g) transition has been recorded in the temperature range of 297-750 K. The measured temperature-dependent rate constants for quenching of O-2(b) by NO can be represented by the expression 5.1 x 10(26) x (T-4) x exp(1338/T). The rate constant for quenching of O-2(b) by I-2 was found to be insensitive to temperature and approximately equal to (6.3 +/- 1) x 10(-11) cm(3)/s over the range of 297-750 K.
