title: Infrared and Raman spectra of phosphatidyl-ethanolamine and related compounds.
abstract: Infrared and Raman spectra of phosphatidylethanolamine from Escherichia coli, L-alpha-glycero-phosphorylethanolamine and 0-phosphorylethanolamine were obtained. Most of the bands were assigned to each vibrational mode based on the N deuteration effect, comparison of the intensity in the infrared and Raman spectra and the depolarization degree measurement in the Raman spectra. The spectra of phosphatidylethanolamine can be interpreted by assuming that the molecule takes the dipolar ionic structure both in non-polar solvent and in solid.
