-
FT-IR transmission spectra of the 3—11 monolayer Langmu ir-Blodgett(LB) films of stearic acid, have been observed compared with FT-IR ATR spectra. As an easily feasible technique, transmission method can offer supplementery information to the ATR one. The intensity ratios between the vibrational bands obtained by the two methods give the orientation aspect of molecular fregments of complecated LB films.
