Infrared transmission spectra of <I>p</I>-nitrobenzoic acid deposited on a Pb film evaporated on a KBr substrate were measured in the Pb film thickness region 0 to 150 nm. The enhancement of the infrared spectrum with the use of the Pb film was first observed. The dependence of the enhancement factor on the Pb film thickness was peculiar, and was discussed together with the structure of the Pb films to clarify the mechanism.
