Heat capacity and thermodynamic properties of thallous fluoride from 5 to 445 K

The heat capacity of TIF has been determined from 6 to 445 K. The nature of the structural transition at 356.3 K, and the excess entropy found (0.225 cal K-1 mol-1, in reasonable accord with that of Cubicciotti and Eding) are discussed. The derived thermodynamic functions permit a re-evaluation of the thermodynamics of the gaseous system, give better concordance with spectroscopic data, and yield a Gibbs energy of formation:Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/33626/1/0000134.pd
