Abstract

A double‐tuned single coil probe for high field metabolic NMR studies has been designed and tested. The resonant coil is a single‐turn of copper foil wound on a quartz cylinder. It is fed by a short length of parallel strip line made of the same material; the feeder is also used as a tuning capacitance. Electrical parameters (quality factors, efficiencies at proton and carbon frequencies) and magnetic resonance data (90° pulse lengths, minimum decoupler power) for lossy samples have been measured. The probe allows for the optimal use of the limited high homogeneity region of a vertical magnet. It shows good sensitivity and efficient decoupling. © 1992 Academic Press, Inc.
