Abstract An ATR attachment was adapted to a FTIR spectrometer. The increased sensitivity makes it possible to measure spectra of transferred monolayers. The characteristic vibrational frequencies of the transferred multilayer systems of two different substance types (octadecanoic acid, octadecylamine) were investigated in dependence on the layer number. A direct correlation between the absorbance and the transferred substance quantity was found. The absence of interaction between the first layer and the germanium surface was evidenced by the lack of a difference between multilayer spectra divided by the layer number, and the measured spectrum of one layer.
