摘要:

L-亮氨酸,C_6H_(13)NO_2,一种人体的基本脂肪族氨基酸的单晶样品,在温度从300到430 K,光谱范围从50到3100 cm ~(-1)的范围内,用拉曼光谱进行了研究。所有波段的暂定分配。对于高温,拉曼光谱上的几个修改,观察到在约353 K,给出证据表明,L-亮氨酸晶体经历结构相变。

英文摘要:

Single crystal samples of L-leucine, C6H13NO2, a fundamental aliphatic amino acid of the human body, have been studied by Raman spectroscopy at temperatures from 300 to 430 K over the spectral range from 50 to 3100 cm-1. A tentative assignment of all bands is given. For high temperatures, several modifications on the Raman spectra were observed at about 353 K, giving evidence that the L-leucine crystal undergoes a structural phase transition.
