The chemical thermodynamic properties of cyclopentanethiol (cyclopentyl mercaptan) in the ideal gas state (0 to 1000/sup 0/K) were calculated by using calorimetric, spectroscopic and molecular structure information. Pseudorotation of the five-membered ring was demonstrated. Experimental studies provided: values of heat capacity for two crystalline forms of the solid (12/sup 0/K to the triple point), for the liquid (triple point to 367/sup 0/K) and for the vapor (390 to 500/sup 0/K); the triple point temperatures; the heats of fusion; thermodynamic functions for the solid and liquid (0 to 370/sup 0/K); heat of vaporization (360 to 405/sup 0/K); parameters of the equation of state; vapor pressure (353 to 446/sup 0/K); and the standard heat of formation at 298.15/sup 0/K.
