A zinc selenide crystal causes total internal reflection in the attenuated total reflectance type of this technique.
A zinc selenide crystal causes total internal reflection in the attenuated total reflectance type of this technique. The two dimensional form of this technique is used to dynamically follow hydrogen bond formation. Unlike a similar technique, this technique requires a compound to have a change in its dipole moment rather than a permanent dipole. This technique can detect certain motions like rocking, wagging, and scissoring. Samples are prepared for this process using Nujol oil or a potassium bromide pellet. Carbonyl compounds have a peak of about 1700 wavenumbers, and several useful vibrations occur in the "fingerprint" region of its spectrum. For 10 points, name this type of spectroscopy that causes vibrations using wavelengths longer than visible light.
