The complete optical-gyration tensor for a monoclinic crystal (2R, 3R)-(+)-C4H6O6 has been determined by the tilter method at a wavelength of 680 nm. The tensor components in terms of rotatory power in relation to the principal axes of the indicatrix were found to be ro11 = 79(7), ro22 = 90(13), ro33 = -70(4), ro23 = -18(8)o/mm, with ro = -12.3(1.0) o/mm in the optic-axis directions. The absolute optical chirality has also been established by combining the structural chirality determination (through the x-ray anomalous scattering) and the signs of the gyration tensor components measured for the same crystal.
