✦ Synopsis


The susceptibility and chemical shielding of CO were determined with regard to the experimental and optimized bond length using coupled Hxtree-Fock calculations with loge gaussian basis sets. The complex Ale/CO was invest&xtcd with respect to the eq:ilibrium geometry and the 13C, "0 and 27Al NMR chemical shielding tensors.

Linear heteronuclear Ir-systems of sp character, when compared with corresponding sp2 systems, show increased shift to higher field for all atoms concerned (0, C, N); acetylene compared with ethylene is a model case. In I7O NMR, the molecules NO+, PhCO+, RCGNO, N=C=O-, RN=C=O and NO2+ were examined
