电子顺磁共振法也叫电子自旋共振法。煤或干馏温度在900℃以下的有机化合物,都具有顺磁共振的性质。在静磁场 H 中,顺磁性物质可吸收频率为 V。的电磁波,在 V。处可观察到吸收谱带。将 V。保持不变,而使磁场 H 在 H。附近改变,可画出电磁波吸收率 x。和外加静磁场间关系的顺磁共振曲线。据试验得知,煤的顺 Electron paramagnetic resonance method is also called electron spin resonance method. Coal or carbonization temperature below 900 ℃ organic compounds, have paramagnetic resonance properties. In the static magnetic field H, the paramagnetic substance can absorb the frequency of V. The electromagnetic wave in V. Absorption bands were observed. V Remain unchanged, leaving the magnetic field H in H. Change near, you can draw the electromagnetic wave absorption rate x. And the relationship between the static magnetic field of the paramagnetic resonance curve. According to the test, the smooth coal
