Techniques for sampling solid organic compounds for FTIR spectroscopy are briefly compared and contrasted. One method, which we call thin solid films, stands out as the method of choice in undergraduate teaching laboratories. Thin solid films are easy to prepare and inexpensive because the sample preparation does not require special equipment. The spectra obtained are of good to excellent quality. Some instructors may not have heard of the technique because it is under-emphasized in most spectroscopy and organic laboratory technique textbooks. The method helps to maximize student use of the current generation of FTIR spectrometers, which are becoming standard equipment in most university-level organic chemistry teaching laboratories.
