Abstract
A modification of the Karplus equation, containing four mutually indep endent structural terms and five adjustable parameters, is put forward . The new structural factor, introduced into this modification is sin (theta(1) + theta(2))/2. The new equation reproduces experimental NMR vicinal coupling constants of norbornenes with a standard deviation of about 0.45 Hz.
