摘要：
By applying the HAUP (high-accuracy universal polarimeter) method, (C3H7NH3)2MnCl4 was found to be optically active in its incommensurate phases, e.g., g33 = 1.1 x 10(-5) in the gamma-phase at 83.0-degrees-C and g33 = 2.4 x 10(-5) in the epsilon-phase at -139.0-degrees-C. The temperature dependence of g33 was obtained. Commensurate domains were found to begin to grow below -139-degrees-C in the epsilon-phase.
