摘要: The proton magnetic resonance spectrum of coumarine oriented in a nematic mesophase has been recorded and analysed terms the proton-proton dipolar coupling constants anisotropic chemical shifts. An analysis isotropic P.M.R. is also reported. N.M.R. spectral parameters indicate that molecule planar structure naphthalene type, with no apparent distortions aromatic ring. internuclear distances derived from experiment are reported, together orientation parameters.
