With the dichroscope, weak trichroism could be observed: colourless, light yellowish green and light green.
Some untreated crystals show a striking trichroism, appearing grayish blue when viewed down the a axis, purple down the b axis, and red, salmon-pink, brown, green or yellow down the c axis.
From the difference spectra calculated by subtracting the structural factor spectrum, it can be seen that the following peaks show significant trichroism: 1477, 1462, 1450, 1416, 1373, 1292, 1264, 1238, 1202, 1169, 1124, 1028, 1000, 974, 961, 929, 834, 731, 695, 580 [cm.sup.-1].
