ABSTRACT:
A method and apparatus for nuclear magnetic resonance spectroscopy is disclosed which expands the decoupling bandwidth. In the method, a pulse train containing a series of radiofrequency pulses joined without interval is applied repeatedly to a sample, each radiofrequency pulse being phased at 0.degree., 90.degree., 180.degree., or 270.degree., and the radiofrequency carrier of the pulse train is reversed in phase at the interval longer than the repetitive cycle of the pulse train asynchronously with the repetition of application of the pulse train.
