WebIR absorption is common for molecular species with a low energy gap among rotational and vibratory states. The net shift of dipole moment in a substance when it vibrates or revolves is a prerequisite for IR absorption. Infrared spectroscopy applications. It helps in identification of the different functional groups present in any given sample. WebSince every functional group is composed of different atoms and bond strengths, vibrations are unique to functional groups, and classes of functional groups (e.g. O-H and C-H stretches appear around 3200 cm -1 and 2900 cm -1, respectively). A correlation chart with various functional group vibrations can be seen in Figure 3. the same roof
