We have used deuterium NMR to investigate the director distribution in a nematic liquid crystal 4-pentyl-4'-cyanobiphenyl, confined between two glass plates and subject to both magnetic and electric fields. The electric field was applied at right angles to the glass surface and the cell was arranged so that the magnetic field of the spectrometer was orthogonal to the electric field. To understand the NMR spectra, measured as a function of the applied electric field, we have calculated the director distribution across the thin nematic film using a continuum theory approach. Numerical solutions of the torque-balance equation with different boundary conditions were used to obtain the director distribution which was then employed to simulate the NMR spectrum. The predicted spectra are found to be in good agreement with experiment provided the effect of the surface anchoring energy is included in the theory together with the elastic energy.
