Notes:
A quantitative study by reflection-absorption infrared spectroscopy (RAIRS) on multilayer systems of Langmuir-Blodgett (LB) poly(amino acid) films has been carried out. Thickness measurements of monolayer and multilayer systems have been made and the results obtained by two well-known equations have been compared. Evolution of the α-helix conformation as a function of temperature in the case of polybenzyl aspartate (PBA) and polybenzyl glutamate LB systems has also been studied by RAIRS. Finally, a Fourier transform infrared transmission study on PBA LB multilayers as a function of temperature has allowed us to draw some conclusions on the orientation of the C=O bonds (amide I) with respect to the dipping direction.
