| Abstract: | Far-infrared measurements reveal a distortion in layer-structured TiCl3 below 217 K. This is explained by the formation of pairs of covalently bonded Ti3+ ions below this temperature. The electronic contribution to the entropy increase above 217 K is attributed to the degree of freedom of the spin of the d electron localized on the Ti3+ ion. |
