Vacuum ultraviolet mass-analyzed threshold ionization spectroscopy of p-, m-, and o-difluorobenzenes. Ionization energies and vibrational frequencies and structures of the cations

초록

Accurate ionization energies of p-, m-, and o-difluorobenzenes and vibrational frequencies of the corresponding cations measured by one photon VUV-MATI is presented. As such, results from quantum chemical calculations are reported which allowed successful vibrational assigments and explanation for other spectral features.
