ResumoNMR of 129Xe has been observed in thin films of xenon frozen onto the surfaces of glass sample cells with various geometries. The 129Xe polarization was enhanced by optical pumping, and the xenon was then transferred to a high-field pulsed NMR spectrometer allowing the observation of strong signals from xenon films of approximately 1 μm thickness. The line shape depends on the film geometry because of the bulk diamagnetic susceptibility χD of solid xenon. The spectral line shape and resonance frequency also depend on temperature.
