一水柠檬酸锂单晶的振动光谱

THE VIBRATION SPECTRUM OF LITHIUM HYDROGEN CITRATE MONOHYDRATE

报道了一水柠檬酸钾（ＬｉＣ６Ｈ７Ｏ７·Ｈ２Ｏ）单晶在不同几何配置下的激光拉曼光谱．对一些振动模进行了归属．从某些拉曼谱峰频率的改变和退偏振，可以判断晶体中存在氢键．由于氢键中的质子转移，导致了晶体动力学无序，使晶格振动外模和某些内振动模表现出较强的各向异性．

The Raman spectra of Lithium hydrogen Citrate monohydrate single crystal in different arrangment was reported.Some of the vibrations have been assigned.From the shift and depolarization of some vibrations,It was concluded that there exist hydrogen bonds in crystal.It is the effect of hydrogen bonds that cause the dynamics disorder of crystal,which induce the anisotropy of the lattice modes and some internal vibrations.
