Abstract
Using threshold photoelectron-photoion coincidence time-of-flight mass spectrometry,the photoionization and photodissociation of methyl chloride in the excitation energy range of 13-17 eV were investigated.CH3Cl+ ions in the A2A1 and B2E excited states were generated,both of which were completely dissociative.CH+3 fragments were mainly produced while CH2Cl+ fragment ions were observed as well.By fitting the time-of-flight profile the kinetic energy released distributions of CH3+ during the dissociation of the energy-selected CH3Cl+ ions were obtained.The dissociation of the CH3Cl+(A2A1) ion followed rapid direct fragmentation while that of the B2E state showed statistical dissociation.Moreover,with the aid of the calculated potential energy surface the CH2Cl+ fragment ions observed in the A2A1 state were generated from the statistical dissociation of the high vibrational excited CH3Cl+(X2E) ions produced by the auto-ionization of the CH3Cl molecule.
