The high temperature experimental spectrum taken at 293 K is shown in Figure where it is compared with several different calculations. The experimental spectrum is broader than the low temperature one and the peak maximum have moved to lower frequencies as would be expected. In the plot we show calculations using static calculations of both hydrogen bonding motifs in Form I along with dynamic calculations including a SH...S only motif (SCI8) and the larger cell containing disorder with a mixture of SH...S and SH...O motifs (DCI32), both at 300 K.
