有機セレン化学において⁷⁷Se NMRから得られる情報

抄録

Recent development in ⁷⁷Se NMR spectroscopy is reviewed and the information available therefrom is critically discussed. After brief discussion on the technical problems inherent in the measurement, an NMR chart is given which illustrates relationship between structures and chemical shifts having the range as wide as 2, 000 ppm. Spin-spin coupling constants pertaining to 77Se can be informative of stereochemistry. Contribution of dipolar interaction between nuclear spins to the total spin-lattice relaxation is negligible in ⁷⁷Se NMR. Spin rotation and/or chemical shift anisotropy are shown to be important here. Recent high research activities in organoselenium chemistry will be strongly aided by this new methodology.
