Calculation of NMR chemical shifts of inorganic compounds by empirical molecular orbital methods

A B S TR A CT - Empirical molecular orbital methods for calculation of NMR chemical shift have been introduced.The INDO perturbation theory including d and f orbitals with SOS and FPT method is emphasised. The methods have been applied to the study of C-13 nuclei in a representative set of inorganic compounds. The results of INDO/GIAO method generally agree well with the trends of experimental results.
