Quench frequency effects on the nuclear quadrupole resonance of orthoiodophenol

Abstract

When the quench frequency of a self-quenched spectrometer is varied, the plot of the ¹²⁷I nuclear quadrupole resonance signal against quench frequency in o-iodophenol, at room temperature, exhibits a number of maxima. Hitherto, analogous plots with chlorine compounds, using self-quenched spectrometers, gave only a maximum; this is briefly discussed.
