The fragment HCO, produced from acetaldehyde by photolysis at 300 nm, was detected by laser-induced fluorescence of B 'A'g 'A' transitions. The fluorescence lifetimes of the HCO B state decrease rapidly as the photolysis energy increases, indicating strong predissociation of the B state. The radiati

Model potential calculations of the B r Du-X r xz transition dipole moment are used in conjunction with the empirica potential energy curves of Vidal and Hessel to calc&te the radiative lifetimes of the vibrational levels of the B r Du state. The lifetimes are nearly independent of the vibrational q
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.
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
