| Abstract: | Model calculations are presented for the multi-photon vibrational spectra for the bound states of the (non-rotating) rare gas dimers HeXe, NeAr and NeXe. The results are used to discuss some of the features of electric dipole spectra that can occur due to the presence of non-zero diagonal dipole matrix elements and/or near-degenerate energy levels. These include multi-photon resonance profiles with oscillatory fringe patterns localized around the main resonance peaks and the possibility of shifts of resonance positions to low frequency relative to the weak field limit. |
