[Recording of high resolution 31P NMR spectra from the surface of a living object].
A surface coil probehead was worked out for the superconducting 50 mm bore magnet of NMR a high resolution NMR spectrometer with the field strength 8,46 T (145.78 MHz for 31P nuclei) with a 50 mm slot. The requirements were analysed for the surface R.F. coil to obtain the greatest possible single/noise ratio at fixed space selectivity. Real penetration depth of the radio-frequency field into the specimen was estimated. Spectra of liver and abdominal muscle of anesthetized mouse were obtained. The probehead may be applied to obtain high resolution 31P spectra in vivo studies of animal organs.
