Abstract

An analysis of both the aromatic and aliphatic portions of the ^1^H NMR spectrum of α‐tetralone has been carried out. Two deuterated derivatives, 2,2‐dideuterio‐ and 4,4‐dideuterio‐α‐tetralone, were prepared to facilitate unambiguous assignment of chemical shifts for the aliphatic protons. The conformation of the 6‐membered alicyclic ring of the molecule is defined by the coupling constants among the aliphatic protons. Benzylic coupling was the only detectable long range interaction between the aliphatic and aromatic protons of the molecule. The magnitude and sign of these coupling constants agree with previous calculations of Wasylishen and Schaefer.

## Abstract The proton NMR spectrum of cinnoline has been measured at high field (250 MHz) and analysed as an H‐8‐de‐coupled ABCXY and H‐4‐decoupled ABCX system. Inter‐ring HH couplings have been determined and discussed in relation to theoretical values obtained using INDO calculations.

## Abstract The ^1^H NMR spectrum of the quinolizidine alkaloid lupinine was studied at 200 and 600 MHz. A full assignment of the ^1^H signals was achieved by application of a variety of NMR techniques, including homonuclear ^1^H NOE difference, 2D δ~H~/δ~H~ COSY and direct δ~C~/δ~H~ correlation ex
