The internal pressures, Pint, of two inorganic liquids: bromine and carbon disulfide were calculated from data in the literature and compared with their cohesive energy densities, ced. The values are in the ranges obtained for common organic liquids, but the ratio of ced/P-int for bromine is larger than might be expected for this non-polar but polarizable substance.
