Photodissociation spectroscopy of Zn+-methanol
We report on studies of the photodissociation spectroscopy of Zn+-methanol complexes in the near-UV region. We observe two absorption bands assigned to Zn+-based 4p <-- 4s transitions in a C-s Zn+-OHCH3 association complex. The 2(2)A'(4ppi) <--1(2)A'(4ssigma) band shows a significant vibronic resonance structure that can be assigned to a combination of both inter-and intramolecular vibrational modes of the complex. The experimental vibrational frequencies are in excellent agreement with the theoretical model predictions. The higher-energy 2(2)A"(4ppi) <-- 1(2)A'(4ssigma) band is strongly coupled to a lower lying charge-transfer state and appears as a structureless continuum. We observe very little reactive branching; rather, charge transfer to CH3OH+ + Zn products dominates the dissociation. These results are compared with previous studies of other main-group- and transition-metal-ion-methanol complexes.
