Specific Far Infrared Spectroscopic Properties of Phospholipids

Abstract EN

We describe the specific spectral signature of different phospholipids and sphingolipids in the far infrared.

Three specific spectral domains have been found: the head group contributions (600 and 480 cm−1); the modes of the torsion motion of the hydrocarbon chains and of the skeleton vibration (460 to 180 cm−1); and the hydrogen-bonding continuum (below 300 cm−1).

Marker bands for individual phospholipids are distinguished.
