Abstract
In this report are presented tables of the principal thermodynamic properties of carbon dioxide along the zero-pressure isobar in the range 100 to 5000 deg R at the intervals indicated by the numbers in parentheses as follows: 100(5)130(10)240(20)500(50)1000(100)2000(200)5000. The data have been computed by the methods of quantum statistical mechanics from best available information regarding (a) the general physical constants, (b) the spectroscopic constants for carbon dioxide, (c) the isotopic weights of carbon and oxygen, (d) the relevant abundance ratios. The computations were carried out in the University of Pennsylvania Thermodynamics Research Laboratory under Project G-12. Computational accuracy well beyond present physical accuracy has been maintained for practical reasons. It is believed that the tables given herein should supersede all previous ones. Although the estimated uncertainties of the values tabulated are still somewhat larger than those for some of the simpler molecules, they are probably small enough for most engineering applications. The calculated values are in fair agreement with those obtained from calorimetric and acoustic-velocity measurements.
