NMR study of palladium methoxide and palladium carbomethoxide complexes
The preparation of palladium methoxide complexes was attempted by reacting LiOCH3 with precursors such as Me2- bpyPdCl2 , [(Me2-bpy)Pd(CH3CN)2 J (BF4 )2 and (Me2-bipy)Pd(OAC)2 which have been synthesized for this purpose. Typically the reactions were done on small scale in an NMR tube and monitored …

The Low-Temperature Specific Heat of Palladium-Hydride and Palladium-Deuteride
The low temperature specific heat of palladium hydride and palladium deuteride, as a function of hydrogen (deuterium) content, has been measured in the temperature range from 1.7 K to 7 K, using high purity, bulk samples of polycrystalline palladium. Loading of the sample with hydrogen or deuterium …

The low temperature magnetic susceptibility of palladium hydride and palladium deuteride
The magnetic susceptibility of palladium hydride for H/Pd< 0.81 and of palladium 4euteride for D/Pd < 0.65 has been measured by the Faraday method at temperatures between 6 and 150 K. The method of measurement has been compared in particular with that employed by Jamieson and Manchester. High …
