Title:HEAVY ATOM VIBRATIONAL MODES AND LOW-ENERGY VIBRATIONAL AUTODETACHMENT IN NITROMETHANE ANIONS
Author(s):Weber, J. Mathias
Contributor(s):Stanton, John F.; Baraban, Joshua H; Thompson, Michael C
Subject(s):Vibrational structure/frequencies
Abstract:We use Ar predissociation and vibrational autodetachment below 2100 wn to obtain vibrational spectra of the low-energy modes of nitromethane anion. We interpret the spectra using anharmonic calculations, which reveal strong mode coupling and Fermi resonances. Not surprisingly, the number of evaporated Ar atoms varies with photon energy, and we follow the propensity of evaporating two versus one Ar atoms as photon energy increases. The photodetachment spectrum is discussed in the context of threshold effects and the importance of hot bands.
