Ce. Mungan et al., ULTRAFAST RELAXATION OF THE FUNDAMENTAL VIBRATIONS OF SH- AND OH- IN POTASSIUM HALIDES, Journal of luminescence, 58(1-6), 1994, pp. 33-36
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.
