The temperature dependence of Raman active modes in monocrystalline Triethylenediamine has been studied by Raman spectroscopy. The linewidths and frequencies of these modes have been measured in the temperature range 110‐330 K (that is the low temperature phase for which T < T c = 351 K). A strong broadening is observed at higher temperatures in this range for the A 2 and E 1g librons. This can be related to the activation of disorder in the low temperature phase.
