Conclusions
-
1.
A calculation of the magnetic screening constants of the protons in the PH3 and P(CH3)3 molecules with the aid of localized molecular orbitals has been carried out for the first time.
-
2.
The contribution to σ from the canonical and localized molecular orbitals coincide with sufficient accuracy.
-
3.
Localized molecular orbitals make it possible to individually evaluate the contribution of the bonds and lone pairs to the magnetic screening constant.
