THE LIFETIME OF THE A.3&U(+) STATE OF N2,

Abstract

The decay of the blue emission from the active nitrogeniodine flame has been measured at iodine pressures down to 0.00014 torr. Extrapolation of the decay rate to zero iodine, pressure yields a value of 0.89=0.41/s for the first-order rate constant in absence of iodine, corresponding to a mean lifetime of 1.1s for the A.3&u(+) state of N2. The rate constants for the reactions N + I2 (yields) NI + I and N2(3&u(+))+I2 (yields) N2(1&G(+)) + I2* are (2.6 = 0.3) X 10 to the -14 power exp (-68 = 34/RT) and (8.3 = 1.2) X 10 to the -14 power cu cm/ molecule/s respectively.
