title: Hydration sites of egg phosphatidylcholine determined by means of modulated excitation infrared spectroscopy.
abstract: Conventional and modulated excitation infrared spectra of egg phosphatidylcholine are measured in the spectral range of 4000-900 cm-1 by modulation of relative humidity with an amplitude of +/- less than 5% at a mean value of 75% (T=30 degrees C). From the modulated-excitation spectrum, hydration sites are found to be the greater than PO2 group, the greater than C=O group and the choline group.
