Second and third virial coefficients for hydrogen

Second and third virial coefficients for parahydrogen have been derived from closely spaced PVT data from 24 to 100 "K. They are in good agreement at 100 OK with published data for normal hydrogen. Analytical representations of the combined data from about 20 to 423 "K are presented which may be useful in computation of thermodynamic functions of the gas. These formulas are related to those resulting from the use of the Lennard-Jones potential.
