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.
