Web11 rows · What functional groups give the following signals in an IR spectrum? A) 1700 cm-1. B) 1550 ... 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.
