REFERENCE MATERIAL FOR ELECTRON SPIN RESONANCE MEASUREMENT, AND SAMPLE ANALYSIS AND ADJUSTMENT AND MAINTENANCE METHOD OF MEASUREMENT DEVICE BY ELECTRON SPIN RESONANCE METHOD USING IT

摘要

PROBLEM TO BE SOLVED: To provide a sample analysis by electron spin resonance method and an adjustment and maintenance method of a measurement device.;SOLUTION: This free radical magnetic parameter determination method is characterized by using an extremely stable perfluoroalkyl radical as a reference material, and mutually comparing positions on spectra of electron spin resonance lines of a free radical or unpaired electron in a sample and the reference material, thereby determining a magnetic parameter represented by g-factor, fine structure constant and superfine coupling constant of the free radical in the sample. This invention includes a free radical analysis method and a method for adjusting and maintaining resolution or sensitivity of an electron spin resonance measurement device characterized by identifying the free radical species based on the magnetic parameter represented by g-factor, minute structure constant and superfine coupling constant of the free radical determined by the above method.;COPYRIGHT: (C)2004,JPO&NCIPI
