Theory of the color of diphenylmethyl ions

Research output: Contribution to journalArticleAcademicpeer-review


Uv spectra of Ph2C:CH2, Ph2C:NH, Ph2CO, and Ph2C:S and the same compds. contg. p,p'-di-OMe or p,p'-di-NMe2 substituents were measured in MeOH and H2SO4. In H2SO4, the carbonium ion is formed with all 12 compds. Self-consistent field calcns. were carried out according to the method of Pariser, Parr, and Pople in order to interpret the uv spectra. The calcd. electron affinities when compared with the polarographic half-wave redn. potentials measured in HCON(Me)2 gave a linear relation. [on SciFinder (R)]
