Imaging the predissociation dynamics of the methyl radical from the 3pz Rydberg state

1 pág.; 1 fig.; XXIX International Conference on Photonic, Electronic, and Atomic Collisions (ICPEAC2015); Open Access funded by Creative Commons Atribution Licence 3.0Direct, time-domain measurements are reported for the lifetimes of the lower-lying vibrational levels of the 3pz Rydberg state of the methyl radical. Lifetimes measured are in the region of hundreds of femtoseconds, and show a decrease with increasing vibrational activity. The mechanism is interpreted with the aid of ab initio calculations.Peer Reviewe
