Swept centerband decoupling as a technique in nuclear magnetic double resonance spectroscopy

Abstract

A technique of doubly modulated radiofrequency irradiation to achieve nuclear magnetic spin-spin decoupling was developed. The effectiveness of this technique, called Swept Centerband Modulation, was investigated by comparison study with other well known techniques. It was found that swept centerband modulation produced an averaging of single coherent frequency decoupling over an adjustable bandwidth. The conclusion drawn from the study was that this technique is not effective for wide band decoupling but very effective for medium to narrow band selective decoupling experiments.
