✦ Synopsis

Abstract

Ethyl 2‐cyano‐3‐methyl‐4‐phenyl‐2‐pentenoate was obtained as a mixture of two geometric isomers. An aromatic solvent induced shift experiment and calculations of the difference in the chemical shifts of methyl protons linked to the double bond lead to the assignation of the geometry of both isomers.

## Abstract The vicinal coupling constant, __J__(12), between the vinyl CH and the ring CH protons in vinylcyclohexane was calculated from a ‘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.

Proton magnetic resonance spectroscopy ( 1 H MRS) has the potential to provide a noninvasive assessment of hepatic lipid composition. The spectral resolution of in vivo clinical MR data is currently limited by the magnetic field strengths available and by motion artifact. Therefore, interpretation o
