Gyration and Permittivity of Ethylenediammonium Sulfate Crystals.
@article{Nichols2016GyrationAP, title={Gyration and Permittivity of Ethylenediammonium Sulfate Crystals.}, author={S. Nichols and A. Martin and J. Choi and B. Kahr}, journal={Chirality}, year={2016}, volume={28 6}, pages={ 460-5 } }
Ethylenediammonium sulfate (EDS) crystals were grown from aqueous solution and cleaved into thin (100-500 micron) plates. The 422 point group of EDS was confirmed by X-ray diffraction. The constitutive relations of EDS crystals were determined through generalized ellipsometry with an instrument that uses four photoelastic modulators (4PEM). The optical rotation at 500 nm, for example, was + 22.9°/mm along the optic axis and - 12.1°/mm perpendicular to the optic axis for the P41 21 2 crystals… Expand
