We report on infrared absorption spectra of the LB film based on ditetradecyldimethylammonium-Au(dmit)2 salt using p-Polarized infrared multiple angle incidence resolution spectrometry (pMAIRS). An intense and broad absorption band appears in a wide wavenumber range associated with the electro-oxidation of the LB film and it can be ascribed to conduction electrons coupling with phonons. Furthermore, as for the broad band, the IP (in-plane) absorbance is greater than that of OP (out-of-plain), indicating a two-dimensional electronic conduction in the LB film.
