A complex Raman spectrum of Cu 2 O has been measured using the Kr laser line at 6471 Å, and comparison with the infrared absorption spectrum is made. An F 2g Raman active phonon, postulated from symmetry considerations and infrared absorption measurements to lie at either 606 or 181 cm −1 , could not be observed. Strong lines are, however, observed at 220, 204, and 192 cm −1 .
