title: [Spectral study on the self-polymerizing reaction of N-diisopropyl phosphoryl amino acids].
abstract: By using polarization sensitive CARS method, five kinds of N-diisopropyl phosphoryl-alpha-amino acids are investigated. They polymerize themselves to form peptide at 55 degrees C 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.
