Electron transfer from state-selected Rydberg atoms to (N2O) m and (CF3Cl) m clusters

Infrared spectroscopic studies on the cluster size dependence of charge carrier structure in nitrous oxide cluster anions

We report infrared photodissociation spectra of nitrous oxide cluster anions of the form (N2O)(n)O(-) (n = 1-12) and (N2O)n(-) (n = 7-15) in the region 800-1600 cm(-1). The charge carriers in these ions are NNO2(-) and O(-) for (N2O)(n)O(-) clusters with a solvation induced core ion switch, and N2O(-) for (N2O)n(-) clusters. The N-N and N-O stretching vibrations of N2O(-) (solvated by N2O) are reported for the first time, and they are found at (1595 ± 3) cm(-1) and (894 ± 5) cm(-1), respectively. We interpret our infrared spectra by comparison with the existing photoelectron spectroscopy data and with computational data in the framework of density functional theory.
