Claeys, E. G. published the artcileHigasi’s method for the determination of electric dipole moments, Application of 2,2-Difluoroacetamide, the main research area is .
The Higasi equation for calculating the dipole moment (CA 43, 7764a) does not require determination of n or calculation of molar refraction. Application to air- and moisture-sensitive compounds would be useful, to avoid the exposure these measurements require. Organometallic compounds of As and Sn and several halo derivs of acetamide and acetaldehyde in several solvents were used and the values for elec. moment were compared, for the classical method, and Higasi’s treatment. Agreement was within exptl. error; there was a maximum deviation of 0.17D., but an average deviation of only 0.05 D. for 14 compounds Solvent effects on measured moments are counted for both classical and Higasi methods.
