Description
The predissociation spectra of the $^{35}$Cl$^-$(H$_2$) and $^{35}$Cl$^-$(D$_2$) complexes are measured at low frequencies between 400 and 800 cm$^{-1}$ in an ion trap at different temperatures. Above a certain temperature, the ligand switching between the two isotopologues $ortho$ and $para$ leads to a strong suppression of the excited hyperfine configuration. Performing the experiment below 30 K and 22 K for Cl$^-$(H$_2$) and Cl$^-$(D$_2$), respectively, we can detect the more weakly bound complexes.
Due to accurate quantum calculations, the bands in the Cl$^-$(H$_2$) complex have been assigned to the intermonomer vibrational stretching mode.
