Abstract

PURPOSE: To realize small-sized decoupling device suitable for small-sized FT-NMR designed to decouple a specific resonance spectrum line existing in the frequency hand for observation by means of high frequency pulse for decoupling.
CONSTITUTION: In a block diagram of FT-NMR equipped with such multiple resonance apparatus, without using variable high frequency generator for decoupling or multiplexer, only a high frequency generator 1 for oscillating high frequency of 60 Hz is used. The sampling period of A/D converter 10 is set by the CPU to the time in inverse number of the frequency from the frequency position of RF pulse to generate resonance signal to be decoupled, and, in synchronism with the sampling period, the high frequency for decoupling to radiate the specimen is pulse-modulated. Using this high frequency pulse for decoupling, a specific resonance spectrum line existing in the frequency band for observation is decoupled.
