The r.f. properties of a high-resolution NMR probehead constructed of epitaxial thin films of hightemperature superconducting ceramics are presented. Operating the probe transmit/receive elements at 25 K significantly decreases the thermal noise of the r.f. coils and increases the probe quality fact

The relationships between 13 C NMR chemical shifts of aromatic carbons and the inter-ring torsion angles (Â) of two phenyl rings in biphenyl and its substituted derivatives were systematically examined. The chemical shifts of C1, C2 and C6 carbons (υ C1 , υ C2 and υ C6 ) of the biphenyl group in the
