本发明公开了一种受激氢键分段长度和能量的声子计量谱学测定方法,该方法需要先采集纯水的拉曼和红外光谱作为参考,然后再用同样实验条件测量通过不同外界激励处理含有氢键的样品的光谱。在对特征峰扣除背景并且面积归一化处理后,减去参考谱,从而得到样品中O:H非键 和H-O共价键长度和能量的即时信息。谱线的形状以及位移则依赖于样品的极化程度,其决定了物质的疏水性,亲水性,极化,溶解度,黏度等特性。该方法适用于对水溶液,血液,体液,尿液,奶制品,食品,药物以及水/蛋白质,疏水/亲水界面等液相和固相体系。
可得信息:
1. 变温:德拜温度与单原子结合能
2. 变压: 弹性模量与能量密度
3. 应变: 单键力常数
4. 低配位:单键长度与能量
5. 氢键(O:H-O)分段激协同弛豫
6. 离子水合层体积与声子寿命关联
