Abstract:

An investigation has been made of a variety of rotor constructions using reinforced materials. 19 mm diameter rotors capable of reliable operation up to 8 kcs propelled by helium gas and containing polycrystalline specimens within a hollow chamber have been constructed. Preliminary work has been done on 13 mm diameter rotors. The turbines have been used to remove dipolar and other forms of broadening of nuclear magnetic resonance spectra of solid materials, with a view to revealing finer spectral structure than has hitherto been observed. In two of the compounds studied electron-coupled spin-spin multiplets have for the first time been resolved with solid specimens. Author
