The significant structure theory of liquids was extended to include liquid hydrogen in its various ortho-para and isotopic forms. It was assumed that liquid hydrogen has a quasi-lattice structure in which the latiicc sites'' are occupied either by hydrogen molecules or holes of molecular size. Such a hole will confer gas-like properties on a molecule which jumps into it and also will give rise to a degeneracy in the solid-like structure. On this basis a partition function can be written down for liquid hydrogen. The thermodymamic properties of para-hydrogen, normal hydrogen, hydrogen deuteride, ortho- deuterium, and normal deuterium were calculated for temperatures ranging from the triple point to temperatures considerably above the boiling point. Critical constants also were calculated. The results were in god agreement with experimental data. In addition, the surface tensions of normal hydrogen, hydrogen deuteride, and normal deuterium were calculated with good results.
