摘要：

We have demonstrated that optical circular dichroism (CD) measurements can be carried out on powders suspended in a liquid medium. The refractive indices of the powder and the suspending liquid must be matched, the suspending liquid must not interact significantly with the solid to be measured and must not absorb in the region where the measurements are carried out. Sodium thioantimonate nonahydrate (Na3SbS4.9H2O) powders obtained by grinding of levo- or dextro-rotatory crystals were found to be excellent examples for the demonstration of this technique. Measurements of the optical rotation for levo- and dextro-rotatory crystals and powders of Na3SbS4.9H2O were also carried out and provided additional characterization of this salt. In the course of developing the CD measurement technique, CD of NaClO3 and NaBrO3 crystals was also measured.
