β¦ Synopsis
Recclved 8 November 1979 hlalomc acid is shown to undergo an mtcrestmg phase transrtlon at 360 K when the two nontqurvalent cyclic hydrogenbonded dimers present in the low-temperature phase become equivalent. * Commurucation No. 56 from the Sohd State and Structural Chemistry Umt.

Infrared spectroscopic studies of C,O films show variation in absorbance and linewidth of the bands across the orientational phase transitions around 280 and 340 K. There is some evidence for the coexistence of phases in the 210-270 K region and for the occurrence of another transition below 200 K.
