A zinc selenide crystal is used in the total internal reflection variant of this technique; more commonly, samples are smeared on (*) potassium bromide salt plates.
This technique is used to distinguish bridging and non-bridging ligands in metal carbonyl complexes and bent versus linear ligands in nitrosyl complexes. The DRIFTS version of this technique requires no sample preparation. Substitutions in a nickel carbonyl complex, in conjunction with this technique, are used to find a ligand's Tolman electronic parameter. A zinc selenide crystal is used in the total internal reflection variant of this technique; more commonly, samples are smeared on (*) potassium bromide salt plates. The fingerprint region lies between 500 and 1500 wavenumbers in the output of this technique, which only detects vibrational modes that change the dipole moment. Carbonyls show up around 1700 wavenumbers in this technique. For 10 points, name this form of spectroscopy that uses wavelengths longer than visible light.
