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