An experiment on the electron spin resonance of colored KCl containing F and M centers was performed at 9500 Mc/sec. Subtracting the contribution from the F centers from the observed resonance curve, we could estimate the shape of the resonance line due to M centers alone, which was found to be Gaussian with the half-breadth of 48 oersteds and g value of 2,000. This result was discussed on the LCAO model.
