Abstract
The proton N.M.R. spectrum, including 13C satellites in natural abundance has been observed for cyclopentadienyl manganese tricarbonyl dissolved in a nematic solvent. From an analysis of this spectrum some information about the geometry of the C5H5 ring in this molecule has been derived. The value of r c-c obtained, 1·37 Å, is appreciably less than the value obtained from X-ray data. By studying the change in the N.M.R. spectrum over a range of temperatures it has been possible to derive a value of -12·30 p.p.m. for the proton chemical shift anisotropy.Keywords
