✦ Synopsis

A new type of double-resonant coil which takes advantage of the properties of a radio-frequency transformer is described. Two concentric loops are wound in close proximity to yield a high mutual inductance. The primary side is tuned to 34 MHz for 31P and the secondary side is tuned to 85 MHz for protons. A single lead allows program control over frequency without the need to rearrange cabling. Proton and phosphorus spectroscopy are made possible over essentially the same volume of interest without the need for repositioning the sample.

## Abstract A double‐tunable probe head based on the slotted tube resonator is described. Its performance at 2.35 T is comparable to that of single‐tunable designs. The main advantages are a large tuning range, a probe volume that is not reduced by the second circuit, and a simple design. © 1990 Ac

## Abstract Insect exoskeleton, multiply labeled with ^13^C and ^15^N, was examined by rotational‐echo double‐resonance (REDOR) and double‐cross‐polarization (DCP) magic‐angle spinning ^13^C NMR. Low levels of incorporation of label make the analysis of these samples a practical test of the relativ
