Thermodynamic Properties of Ideal Gaseous Methanol

Abstract
New calculations are presented for the thermodynamic properties of methanol which are based upon the most recent spectroscopic data. The molecular constants related to the internal rotation are now well established. The vibrational assignment is discussed and additional arguments are presented for the correctness of the selections of Herzberg and Plyler. The method of statistical calculation is essentially that of Halford, but avoids an approximation. Complete thermodynamic functions are tabulated for the range 100 to 1000°K. Agreement with experimental thermodynamic data is satisfactory.
