Abstract
One‐ and two‐dimensional NMR spectra of Tröger's base, (±)‐2,8‐dimethyl‐6__H__,12__H__‐5,11‐methanodibenzo[b,f][1,5]diazocine labelled on one of the nitrogen atoms, have been used to determine the chemical shifts, coupling constants, and Δ^13^C(^15^N) isotope shifts.

The ' H and '% NMR spectra of 15 modified representatives of Troger's base were recorded and the corresponding signals assigned. In 'H NMR, the appearance of the AABB'CC'(XX) system, after irradiation of H,(H,), is deceptively simple and should not be first-order analysed. The 13C chemical shifts an
