Vibrational analysis of methyl cation - rare gas atom complexes: CH-Rg (Rg=He, Ne, Ar, Kr)
Jan Meisner, Philipp P. Hallmen, Johannes Kästner +1
The vibrational spectra of simple CH-Rg (Rg=He, Ne, Ar, Kr) complexes have been studied by vibrational configuration interaction (VCI) theory relying on multidimensional pote…
