Abstract
Dielectric measurements in the MHz region of bacteriorhodopsin (bR) in aqueous solution have shown the existence of β1-dispersion with five distinct parts. This dispersion and the β-dispersion at low frequencies conform approximately to the Debye relaxation equations. The derived apparent relaxation times showed dependence on various physical parameters. The relaxation effect at low frequencies is attributed to the reorientation of bR chromophore within the purple membrane (PM) fragments. The mechanism which gives rise to the β1-dispersion may well be due to the Maxwell-Wagner effect, although the first two parts of the dispersion could also be attributed to counterion relaxation or to bR reorientation.
