[EX Q]: The attenuated total reflection type of this can be used on compounds with a low surface area, while the diffuse reflectance type can be used to study samples that are not sufficiently transparent. The multiplex advantage explains the use of the Fourier Transform type of this. Diatomic bonds are generally not found in the fingerprint region, and the stretching seen using this technique generally occurs at higher frequencies than the bending. Most types of this use some sort of absorption, because each bond in the molecule will absorb only its characteristic frequency. For 10 points, name this type of analytical technique, which categorizes compounds based on the frequency of the vibration of its bonds when exposed to radiation of waves longer than those of visible light.
