Single-photon direct absorption and resonance-enhanced multiphoton ionization excitation spectra were recorded for CHJ in a jet-cooled molecular beam. The rovibrationally cold molecules yield lineshapes that are lifetime broadenend by predissociation. Lorentzian fitswere used to extract lifetimes f
Lifetimes of the vibrationless levels of the B state of CHJ and CDs1 have been measured using a tunable deep UV ( = 200 nm) femtosecond source. The lifetimes of the predissociated states are 1.38 + 0.20 and 1.84 k 0.13 ps, respectively. These values are compared with those obtained by indirect measu
