stereochemical trends of geminal and vicinal (77)Se-(1)H spin-spin coupling constants has been carried out by means of high-level theoretical calculations in combination with experiment. The marked dihedral angle dependences for both types of couplings accounted for the lone pair effect in the case of geminal coupling constants and the Karplus-typerelationship for vicinal couplings have been established
