   Also found in: Dictionary/thesaurus, Encyclopedia, Wikipedia 0.01 sec.
infrared spectroscopy (inˑ·fr·redˈ spek·trsˑ·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.
