in·fra·red spec·tros·co·py

the study of the specific absorption in the infrared region of the electromagnetic spectrum; used in the study of the chemical bonds within molecules.

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.
