Photoacoustic spectroscopy of purple membrane fragments. Evidence for disorder during photocycle.
A strong band at 412 nm has been observed in the photoacoustic spectrum of partially dried purple membrane, peaking sharply at a modulation frequency of about 70 Hz. This may be explained in terms of a disorder-order transition.
