  • Abstract
    The polarizability theory of optical activity is used to investigate the crystal structure peculiarities of disordered langasite family crystals. An optical rotation was calculated as the function of site occupancy of mixed 1a, 2d and 3f Wickoff position for various Ca-gallogermanate structure type crystals.
