Pulsed laser photolysis/laser-induced fluorescence (LIFI is utilized to measure absolute rate constants of CH radical reactions as a function of temperature and pressure. Multiphoton dissociation of CHBr, at 266 nm is employed for the generation of C H (X'I1) radicals. The C H radical relative conce

Cesium atoms solvated with polar solvents, Cs(H,O)., Cs(NH,), and Cs(CH,CN),, are studied by one-photon ionization and time-of-IX&t mass spectroscopy. The ionization potentials of Cs(H,O), and Cs(CH,CN), are found to be constant for n& (3. I eV) and n 2 I2 (2.4 eV), respectively, while that for Cs(
