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 laser Raman spectra of single crystals of potassium citrate monohydrate (LiC6H7O7 · H2O) under different geometric configurations were reported. Some vibration modes are attributed. From the change and depolarization of the frequency of some Raman peaks, it can be judged that hydrogen bonds exist in the crystal. Due to the proton transfer in the hydrogen bond, the crystal dynamics is disordered, which makes the lattice vibrational external modes and some internal vibrational modes show strong anisotropy.
