Fourier transform infrared photoacoustic (FT-IR/PA) spectroscopy combined with the reflection-absorption (RA) technique is demonstrated for Langmuir-Blodgett (LB) films deposited on metal substrate FT-IR/PA and FT-IR/PA/RA spectra can be taken on the same LB film. By the use of FT-IR/PA and FT-IR/PA/RA methods. Spectra corresponding to transmission and RA spectra can bee identified for the same LB film on a metal substrate. The molecular orientation of the LB film can be analyzed with the use of these spectra.
