Comments:
The dynamics of ground state Cl(2P3/2) atom reactions with methanol, methanol-d1 , ethanol, and dimethyl ether were studied both experimentally and theoretically. The rotational quantum state population distributions of the nascent HCl(?u?) products were probed by 2+1 resonance-enhanced multiphoton ionization in a time-of-flight mass spectrometer. Nascent HCl(?u?=0) reaction products at mean collision energies in the range of 5.6-6.7 kcal/mol, exhibit distributions of population over rotational levels that all peak at J?3-5. The average rotational energies of the HCl(?u?=0) products for the respective reactions were determined. The results are interpreted with the help of
