甘油溶液声速、核磁共振信号峰面积变化规律的微观机理研究

摘要

利用超声光栅法和核磁共振法测量了不同浓度甘油溶液的声速和核磁共振信号峰面积,对其实验原理和实验现象进行了解释,将声速与氢键含量、核磁共振信号峰面积与能级跃迁相联系.结果表明:随着甘油溶液浓度的升高,声速随氢键含量的增加而增大,信号峰面积则随氢核数目的减少而减少.%Velocity and signal peak area of different concentration of glycerin solution were measured by ultrasonic grating method and nuclear resonance method, and the explanation of regularity and phenomenon was given. That the velocity was connected with the number of hydrogen bond and the signal peak area was connected with the energy level transition. The result show that with the increase of glycerin solution' s concentration, the velocity is in-cresed ularity with the number of hydrogen and the signal peak area is decreased with the number of proton increased.
