## Abstract The vicinal coupling constant, __J__(12), between the vinyl CH and the ring CH protons in vinylcyclohexane was calculated from a β€˜partial molecule’ six‐spin system. The 100 and 270 MHz results are in good agreement; those at 60 MHz were, however, still inaccurate in this approximation.

## Abstract The ^1^H NMR spectra of imidazo [1,2‐__a__]pyrimidine derivatives have been analysed to study the aromatic character and protonation behaviour of this system. By employing the β€˜ring currentn’ model and calculations based on the coupled Hartree‐Fock method it can be deduced that a large
