vibrational-rotational
Infrared (IR) spectroscopy is an analytical technique used to determine the bonds and functional groups in the structure of chemical compounds. The advantage of this technique is that any sample in virtually any state can be studied. For example, powder, paste, a mixture, gas films, and ________ can be easily examined.
