Insight Into

Nozzle-cooled BrCl was excited with tunable laser radiation at selected wavelengths between 389 and 500 nm. The chlorine atomic fragments in their Cl*(2P1/2) and Cl(2P3/2) state were stated-selectively probed by resonance-enhanced multiphoton ionization. The branching ratio (Cl*/(Cl + Cl*)) was measured as a function of the excitation wavelength. The relative Cl* yield reaches a maximum at around λphot = 460 nm. Decomposition of these branching ratios into Cl and Cl* photofragment yield spectra provides insight into the BrCl B-state 3П(0+) non-adiabatic dissociation dynamics. Our results suggest that the dissociation mechanism involves non-adiabatic transitions among 0+ potential energy curves.

Dissociation Dynamics

The methyl iodide A-band photodissociation is investigated using a photofragment time-of-flight technique coupled with state specific detection of either the iodine atom or methyl radical dissociation products by multiphoton ionization. The method is quite general and allows the fragments' velocity and spatial distributions to be determined simultaneously with their rotational, vibrational and electronic excitation. It is shown that methyl product from two competing dissociation channels, one direct, the other necessitating an initial surface crossing, can be clearly distinguished by virtue of the characteristic translational excitation in each. The different rotational excitation which is observed in these two channels is discussed in terms of the dissociation dynamics in the methyl iodide A-band continuum.
