Abstract

INDOR experiments on heptahelicene have revealed the existence of positive ^5^J (epi), negative ^4^J (peri) and |^4^J| (peri) cross‐ring couplings.

## Abstract The ^1^H n.m.r. spectra of two naphthalene derivatives have been completely analysed. The advantages of the INDOR technique have been illustrated in the determination, magnitudes and signs, of small couplings in complex spin systems. A splitting of 0.07 Hz has been resolved in the 100 M
