Abstract

PURPOSE: To reduce measuring time by switching the combination of the single decouple mode of a proton wideband decoupler, a wideband decouple mode and the frequency of a decouple high frequency.
CONSTITUTION: Signal CW from single mode oscillator 5 and signal WIDE from wideband mode oscillator 6 are switched by mode change switch 7 and are inputted to probe 12 via modulator 3. On the other hand, the signal of measuring pulse generator 10 is supplied to probe 12 and becomes an irradiation pulse to actuate a free induction attenuation signal. This is synchronized with the alternately repeated data take-in period and non take-in period, and thereby the designated combination of signal from oscillator 5, signal WIDE from oscillator 6 and the frequency of pulse generator 10 is switched. Consequently, off-resonance or selective decouple, with overhauser effect retained, can be operated, and measuring time can be reduced.
