Abstract

Measurement of optical rotation in RbTiOASO(4) (RTA) with the tiller method resulted in an optical rotation Of Q(12) = +17(3)degrees/mm at a wavelength of 670 nm, when a (100) sample was tilted about [001]. A tilt about [010] showed no rotation, as expected from the directional dependence of optical rotation calculated from the tensor in point group mm2. The absolute Miller-indices of the samples were found using X-ray anomalous scattering. The calculations with a dipole-dipole model show that the As5+-ions in RTA correlate with the main structural contribution of the optical rotation. However, there seems to be an even larger intrinsic contribution due to the Ti4+ - ions as a result of the distorted octahedral co-ordination with oxygen.
