Abstract
Data on the integral intensities of the Νv(P-H) bands of di-n-propyl phosphite and diisopropyl phosphite in different media have shown that in strong protonacceptor solvents the P-H group of the dialkyl phosphites examined is able to form weak hydrogen bonds. Beside this, association of liquid di-n-propyl and diisopropyl phosphites takes place by a dipole-dipole mechanism. Variations in the spectra as the medium, the temperature, and the phase are varied point to conformational nonuniformity in the di-n-propyl and diisopropyl phosphite molecules. The Ν(P-H) band is conformationally sensitive. In the crystal, a less polar, gauche, gauche form is achieved.
