A Nuclear Magnetic Resonance Study of Norbornadiene Partially Oriented in a Nematic Phase

Abstract

The n.m.r. spectrum of norbornadiene partially oriented in a nematic phase has been measured, and the geometry of the proton skeleton has been determined. The results are compared with several electron diffraction studies, and are only consistent with those in which the angle C₁C₇C₄ is approximately 92°.
