13种氨基酸的拉曼光谱：L-丙氨酸、β-丙氨酸、L-天冬酰胺、L-天冬氨酸、L-谷氨酸、L-谷氨酰胺、甘氨酸、L-甲硫氨酸、L-脯氨酸、L-丝氨酸、L-苏氨酸、L-色氨酸和L-酪氨酸在户外使用来自Ahura和Delta Nu制造商的两台便携式拉曼仪器获得，两者都具有785 nm激光激发。这两种仪器都提供了高质量的拉曼光谱，但对现行的实验条件有可变的依赖性。在这些实验中获得的数据将为选择合适的拉曼光谱仪提供信息，用于在地球极端环境和地外探索中，特别是使用机器人仪器在行星表面和次表面进行光谱搜索的生物分子的现场检测。(c)2010 Elsevier B. V.保留所有权利。
Raman spectra of 13 amino acids: L-alanine, beta-alanine, L-asparagine, L-aspartic acid, L-glutamic acid, L-glutamine, glycine, L-methionine, L-proline, L-serine, L-threonine, L-tryptophan and L-tyrosine were acquired outdoors using two portable Raman instruments from the Ahura and Delta Nu manufacturers, both with 785 nm laser excitation. Both instruments provide quality Raman spectra with nevertheless a variable dependence upon the prevailing experimental conditions. The data acquired in these experiments will inform the selection of suitable Raman spectrometers for the in-field detection of biomolecules of relevance to the search for life signatures spectroscopically in terrestrial extreme environments and in extraterrestrial exploration, especially of planetary surfaces and subsurfaces using robotic instrumentation.
