Conclusions
-
1.
A semiempirical calculation of the NMR-31P chemical shifts for a number of compounds of tetra- and pentacoordinated phosphorus, using data on the populations of the p- and d-orbitals of the phosphorus atom by the CNDO calculation method, gave satisfactory agreement with the experimental chemical shifts.
-
2.
The unbalancing of the p-electrons of the fluorine atoms was calculated for certain organophosphorus molecules and varies directly with the NMR-19F chemical shift.
