NMR Measurement Method
First Claim
1. An NMR measurement method comprising the steps of:
- applying RF power of a frequency not affecting measurement of an NMR signal to a detection coil or the RF irradiation coil such that reflected RF power is produced; and
detecting an increase in the temperature of the detection coil or the RF irradiation coil from the strength of the reflected RF power.

Abstract
There is disclosed an NMR measurement method and NMR apparatus in which the temperature of the NMR detection coil or the RF irradiation coil hardly varies if pulsed RF power is applied to the coil during NMR measurements. The apparatus includes the detection coil or the RF irradiation coil, a first RF power application means for applying RF power of a frequency necessary for measurement of NMR signals, a second RF power application means for applying RF power of a frequency not affecting the measurement of NMR signals, and a control means for controlling the two power application means such that the sum of the RF power applied to the coil from the first application means and the RF power applied to the coil from the second application means is kept almost constant.
