Infrared absorption spectra of 5-bromo-9-hydroxyphenalenone were measured and analyzed in detail as a function of temperature. An intense and broad peak at 83 cm 21 occurring in the protonated crystal, but not in the deuterated analog, arises from the coherent tunneling motion of the hydrogen in the
