A variation of this technique uses signal averaging to improve signal-to-noise through Jacquinot’s advantage. (15[1])Detectors made of DLATGS are found in devices for this technique, which often uses matrix isolation. A variant of this technique (-5[1])often paired with ATR generates data in the form of interferograms. (-5[1])Holding up two, three or four fingers is a common mnemonic when analyzing aromatics in this technique. (15[1]0[1]-5[1])Rows that contain x, y or z in a character table correspond to this technique. (-5[1])A (*) potassium bromide disk or Nujol (“NEW-jull”) mull (10[1])can be used to prepare samples for this technique. This technique observes changes in dipole moment due to molecular vibrations, (10[2]-5[1])and identifies functional groups in the fingerprint region. For 10 points, name this spectroscopic technique named for radiation with a wavelength longer than visible light. ■END■ (10[2]0[2])
