Calculations using large atomic natural orbital (ANO) basis sets and high levels of correlation treatment are employed to determine the radiative lifetime for the t= I-5 levels of the X 'Z+ state ofNO+. The theoretical lifetimes, which agree well with prewous theoretical estimates, are estimated to
The 193 nm photolysis of acetylene has been used as a source of &(B 'Z: ) radicals, which are subsequently detected by laserinduced fluorescence technique. The pressure-dependent collisional lifetimes of this radical are experimentally determined by delaying the probe laser with respect to the photo
The radiative lifetime of the NO (b 4~-, U' = 4) state has been measured using the high frequency deflection technique. The result, 9.23 + 0.90 Ixs, is in reasonable agreement with ab initio calculations but a factor of two larger than an earlier experimental determination.
