## Abstract Proton magnetic resonance spectra of several monoβ and disubstituted benzaldehydes were studied using CW, INDOR and double resonance techniques. It was verified that substitution in the __para__ position has no effect on the longβrange coupling of the aldehydic proton with the ring prot
It is shown that the spin-orbit coupling constant, f, far a series of 3d transition metal ions may be rtkfzctoriIy evaluated using approximate double-zeta SCF functions. The radial distance dependence of [ has been calculated, and the results indicate that the reduction of 4 below the free-ion value
