The remarkable "softening" of a librational mode in thulium azide (TIN,) around its 240 K phase trz-nsition has been observed by Fkman spectroscopy. Arhn-r~onic coupling between this mode 2nd the rotational displacerr,ent parameter of the transition is proposed in terms of the theoretical model of C
