IR Spectroscopy

Professor Dave introduces IR spectroscopy, a technique used to study the interaction of light and matter to determine molecular structures. He explains how infrared light affects molecular bonds, causing vibrational motions like stretching and bending. The IR spectrum is analyzed by examining wave numbers and transmittance to identify functional groups in a molecule. Key functional groups like OH, CH, and carbonyl are discussed, highlighting their unique absorption patterns. The tutorial emphasizes that IR spectroscopy helps identify functional groups but not the precise molecular structure.
