Photoelectron-photofragment coincidence studies of NO-_X clusters (X = H2O, CD4)Faculty of Science - Papers (Archive)
AbstractThe 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 energy and kinetic energy release from NO -(CD4). Consideration of the maximum available kinetic energy allows the binding energies to be detemined as 0.57 and 0.07 eV for NO -(H2O) and NO -(CD4), respectively.
