Abstract

The nonresonant two-photon MATI and ZEKE spectra of CH2CO+ and CD2CO+ were recorded. Fundamental wave numbers of several (six for CH2CO+ and seven for CD2CO+) normal vibrational modes of the ̃X2B1 electronic ground state of both ketene cation isotopomers were determined. The v5, v6, v8, and v9 nontotally symmetric vibrational modes were observed in the ̃X2B1 state of the ketene cation for the first time. The higher resolution of MATI and ZEKE techniques as compared with the traditional photoelectron made it possible to partially resolve the rotational structures of some of the bands.
