FT-IR spectroscopy for exposing the CH vibrational bands from the polar parts of phospholipids

For the sake of overcoming this lack, we have excogitated a set of deuterated derivatives of 1,2-dimyristoyl-sn-glycerophosphocholine tailor-made such as to disentangle all the CH and CH2 unities present, and studied these substances as well as methylphosphocholine as a lipid headgroup model in the solid state by means of FT-IR spectroscopy. The data are considered in terms of assessing the usability of the material, especially with respect to the observed IR bands due to the minor components. Isotopic shift factors are regarded and assignments for the different species are proposed and discussed.
