Ab initiu methods are now known to reproduce satisfactorily the nuclear magnetic shielding for various first-and second-row nuclei. In this paper, calculated values for the '19Sn shielding in SnH,, Sn(CH,), and SnCI, are presented and compared with the recently established absolute shielding scale.
31 P and 13 C chemical shielding values, iso , were calculated for a series of phosphaalkenes X-P CY 2 with a variety of substituents such as X H, CH 3 , F, Cl, Br, OH, NH 2 , PH 2 , SiH 3 , CN and Y H, CH 3 , NH 2 , SiH 3 , using the GIAO procedure at the RHF/6-311 C G(d,p) and RHF/6-311 C G(2d,
A direct method for the ab initio calculation of the magnetic susceptibility and chemical shielding tensors based on the individual gauge for localized molecular orbitals (IGLO) formalism is introduced. "Direct" in this context means we avoid storing the two-electron repulsion integrals in favor of
