摘 要: | We have designed a new INDO/σ program which may calculate the NMR chemical shifts with both appropriate computer time and accuracy.The ~(190F and ~(13)C chemical shifts for simple CF_nCl_(4-n) compounds and a transition metal complex, Fe(C_5H_5)(CO)_2CN have been calculated accordingly. A satisfactory linear relation ship is found between the calculated value and experimental data.It affords a reliable basis for the calculation of chemical shifts of large molecules and transition metal complexes.
