Determination of optical activity in monoclinic crystals of tartaric acid, , using the `tilter' method

The complete optical-gyration tensor for a monoclinic crystal of 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 , with 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.
