Abstract

FT-IR photothermal beam deflection (PBD) spectra were recorded of solids submerged in liquid CCl₄ and in C₂Cl₄. Some PBD effects are described. Submerging the sample leads to PBD signals 40 times larger than those found with the sample in air, but the signal-to-noise ratio of FT-IR/PBD spectra is only increased by a factor of ten. Certain aspects of the technique and its utility are discussed.
