A gradient magnetic field coil is excited by coil exciting means, thereby a gradient magnetic field being generated. The gradient magnetic field generates eddy current in an eddy current generating portion, the magnetic field due to this eddy current disturbing the gradient magnetic field. Means for compensating the magnetic field due to the eddy current is disposed, this means having a transmission function representing an inverse of the transmission function of a gradient magnetic field system including the gradient magnetic field coil and the eddy current generating portion.

Nuclear magnetic resonance exciting device

A spectrophosphorimeter with a single spectrometer so as to obviate the need of a couple of spectrometers of conventional spectrophosphorimeters, wherein one spectrometer is operated as an excitation-side spectrometer only when the light is allowed to pass a light interceptor, and the other spectrometer works as a phosphorescence-side spectrometer only when the light is substantially interrupted. The single spectrometer is used on the excitation side when the light is allowed to pass and on the phosphorescence side when the light is interrupted.
