infrared spectroscopy (inˑ·fr

·redˈ spek·tr

sˑ·k

·pē),

n an instrumental technique used to identify substances—in particular the functional groups present in organic compounds by measuring their absorption of infrared radiation over a range of frequencies. The absorption pattern is then compared to the infrared spectra of known substances for identification.
