Abstract
Transfer of electronic energy from the resonance states Ar(1P1) and Ar(3P1) to diatomic nitrogen, hydrogen, and nitric oxide has been studied with a time‐resolved quenching technique. Rate constants for energy transfer were deduced from the changes of the rate of decay of excited states corresponding to known changes of the density of the diatomic molecules. For Ar*–N2 the rate constants were 5.4×10−11 and 0.8×10−11 molecule−1⋅cm3 sec−1 for Ar(1P1) and Ar(3P1), respectively. For Ar*–H2, the measured rate constants were 22×10−11 and 21×10−11 molecule−1 cm3 sec−1 for Ar(1P1) and Ar(3P1), repectively. The results for nitric oxide were 54×210−11 and 32×10−11 molecule−1 cm3 sec−1 for Ar(1P1) and Ar(3P1), respectively.
