Photoelectron-Photofragment Coincidence Studies Of No-_X Clusters (X = H2o, Cd4), Berwyck Poad, Christopher Johnson, Robert Continetti
Berwyck L. J. Poad
The dissociative photodetachment of NO -(H2O)and NO -(CD4) anion clusters was studied at 775 nm (1.60 eV) using photoelectron-photofragment coincidence spectroscopy. The correlation between the photoelectron and photodetached neutral spectra indicates vibrational excitation in the recoiling NO neutral fragments from NO-(H2O), with a progression consistent with vibrational excitation up to v(NO) = 3 in the products. The correlation remains when D2O is substituted for H2O, implying the NO vibrational mode plays a role in the dissociation coordinate of the complex. In contrast, no correlation was observed between photoelectron kinetic …
