β¦ Synopsis
Carbon and proton NhfR chemical shifts are calculated for some small polyntomic molecules using ab-initio rnolecu!nr orbital theory with a minimal basis set of gauge invaiant atomic orbit& (GWO). The results are compared with those obtained without gauge factor!; and both sets of calculated values are compared with experiment. The overall agreement with experiment is much better for the GIAO results parkularly for proton chemical shifts.

## Abstract Plain rules founded in a theoretical background are presented that can be used to determine the structure of selenium compounds on the basis of __Ξ΄__(Se) data and to predict __Ξ΄__(Se) data from a given structure with satisfactory accuracy. As a first step to establish such rules, the or
A macroscopic solution polarization free-energy functional is combined with semiempirical molecular orbital theory to study shifts of electronic absorption energies for several molecules in solution. The present method requires calculation of the induced electrostatic potential on the van der Waals
The ESCA chemical shifts of carbon and nitrogen in a variety of chemical ekironments have been calculated from the energy difference (aE) between the pgent molecule and the isoelectronic nitrogen and oxygen containiiv& Lotions using the hIINDO/I valence electron SCF MO method. For the case of carbo
Formulas for calculating NMR chemical shifts at second-order many-body perturbation theory using the gauge-including atomic orbital method are presented and their implementation is discussed. The method is applied to study correlation effects on calculated ~70 chemical shifts,
