Abstract
The vibrational relaxation times of SH- and OH- in potassium halides, measured by incoherent laser saturation, vary from 0.8 to 7 ns at 1.7 K. A librational side band at +300 cm-1 provides a possible decay chan nel. The strength of this mode is strongly temperature dependent, poss ibly owing to barrier hopping.
