AbstractInfrared spectra of dipalmitoyl phosphatidylcholine (DPPC) bilayers in water have been measured over the pressure range 0 to 35 kbar. Discontinuities in the pressure dependencies of various infrared spectral parameters indicate that structural phase transitions occur at 1.7, 4.8 and 15 kbar. Pressure-induced changes in the CH2 bond angle and in the chain orientation are evident. Pressure also affects the dispersion of,various vibrational frequencies resulting in drastic changes of the Fermi resonance interaction between the symmetric CH2 stretching mode and the continuum of the binary combination of the CH2 bending mode.
