dc.description.abstractThe effect of various solvents upon the N-H vibrational frequencies of phosphoryl trisanilide (PTA), thiophosphoryl trisanilide (TTA), phosphoryl triscyclohexylamide (PTC) and thiophosphoryl triscyclohexylamide (TTC) was measured. The solvent shifts for the different amides are correlated and there is also some correlation between solvent shifts and Gutmann''s solvent donicities. For the calculation of the solvent shifts a better linear relation is obtained through an equation of 3 terms which takes into account the donicity, the acceptor number, the dipole moment and the relative permittivity of the solvent. The last term considers the interaction of the solvent dipole moment with the induced dipole on the N-H bond. These correlations are discussed.
