An adaptation of the HTP (high-temperature photochemistry) technique to make it suitable for the study of metal atoms is described. In this, the first such HTP work, sodium salts are evaporated and ground-state atomic Na is generated by pulsed excimer or flash lamp photolysis. For the reaction Na + O{sub 2} + N{sub 2} {yields} NaO{sub 2} + N{sub 2} (1), we thus determine log k(590-1,515 K) = {minus}44.29 + 11.70 log T - 2.34(log T){sup 2} (cm{sup 6} molecule{sup {minus}2} s{sup {minus}1}) with a 2{sigma} confidence interval of 21-26%, depending on temperature, which figures include a liberal allowance for potential systematic errors.
