Abstract

Specific details are given for double-tuning the Varian V-4333 probe for use in the following heteronuclear magnetic double resonance experiments: observe ¹H at 100 MHz; irradiate ²H, ¹⁹F, or ³¹P; observe ¹⁹F at 94 MHz; irradiate ¹H, ²H, or ³¹P. An inexpensive source of audiofrequency-noise is described which, in conjunction with the double-tuned probe and several commercially available components, constitutes the basis of a versatile heteronuclear-decoupler. Examples are given which illustrate the effectiveness of this decoupler. Double-tuning of the Varian V-4333 probe by introducing a second transmitter coil is also described.
