摘要：

Infrared spectra in the range of 530-1400 cm(-1) are presented for tantalum oxide cluster cations TaxOy+ (x = 3, 4 and 6). These spectra are obtained via multiple photon dissociation (MPD) spectroscopy of free cluster cations moving in a molecular beam. The IR spectra for TaxOy+ are compared to spectra of NbxOy+ as well as to the experimental data available for vanadium oxide cluster cations from IR-MPD spectroscopy. For TaxOy+ and NbxOy+ the IR spectra exhibit very strong similarities (including the band positions), whereas absorption bands in VxOy+ are relatively blue-shifted by about 20-40 cm(-1).
