摘要:

IR intensity and ESCA measurements have been used to determine the distribution of atomic charges in the bis (triphenylphosphoranylidene) ammonium ion. The central nitrogen atom has a charge of -0.5 whereas the two phosphorous atoms have positive charge (+0.9). From the IR intensity data and13C-NMR parameters it was possible to estimate the charge of each phenyl group. The result (-0.05 a.u.) is in good agreement with the result from the ESCA investigation.
