Abstract
HCl+(A) was selectively prepared in the v′=0, 3, 5, and 6 levels using ion impact excitation. The resulting A–X spectra are largely free from band overlap. From intensity measurements on 16 bands, the electronic transition moment function M(R) was derived in the region of R=1.1–1.8 Å. Computer simulations based on this M(R) function were performed both for these and for additional spectra excited by electron impact. In all cases an excellent reproduction of the measured spectra was achieved. The M(R) dependence obtained in this work agrees very well with a large-scale ab initio calculation.
