| Abstract: | The vaporization enthalpies (ΔH vap) of 97 primary, secondary, and tertiary alkylphosphines and alkyl(aryl)phosphines with different spatial structures were calculated using the Trouton and Wadso equations and the first-order topological solvation index1χs. The contributions of the H2P and HP groups and the phosphorus atom to the vaporization enthalpies of primary, secondary, and tertiary phosphines, respectively, were calculated. The results obtained can be used in calculations of ΔH vap for related phosphorus compounds. For Part 16, see Ref. 1. Translated fromIzvestiya Akademii Nauk.
