氮-磷酰化氨基酸自聚反应的光谱研究

SPECTRAL STUDY ON THE SELF POLYMERIZING REACTION OF N DIISOPROPYL PHOSPHORYL AMINO ACIDS

用偏振ＣＡＲＳ研究了五种氮－磷酰化氨基酸的自聚肽反应。通过观测到的反应前后的振动光谱图，以及对顺式和反式肽键异构体振动频率的理论计算，确定所生成的肽键为顺式结构，并对各振动频率进行了标识。

By using polarization sensitive CARS method,five kinds of N diisopropyl phosphoryl α amino acids are investigated.They polymerize themselves to form peptide at 55℃ for 40 hours.The vibration mode spectra prior and after the reaction are recorded.With the help of theoretical calculation,the configuration of these peptides are inferred to be trans form and the specificities vibration modes are assigned.
