✦ Synopsis
A new approach for NMR shielding constant calculations in the framework of coupled density functional theory (DPT) with individual gauges for localized orbitals is presented. A new model is suggested for an exchange-correlation potential response linear with respect to an external magnetic field suitable for practical applications in the framework of DFI. The calculations were carried out using a modified version of the deMon program. The results are in good agreement with those of the best coupled Hartree-Fock approaches taking into account electron correlation effects.
