Electro-Optical Responses of Chiral Substances
The Jones matrix for chiro-birefringent systems has been obtained. The matrix appears as a function of γ = (α2 + β 2)1/2, where α is the rotation angle, β is a half of the optical retardation due to birefringence. The matrix is quite general and can be used without any limitation, provided that the system is homogeneous and the axis of birefringence can be well determined. By use of the matrix, a general equation for light intensity in an optical system composed of a chiro-birefringent medium sandwiched in between two polarizers is derived. A convenient optical system to measure an anisotropy of optical rotation by use of conventional electro-optical devices is proposed. Effects of slight deviation of the polarizer from a proper orientation of the axis and of stress birefringence in the cell windows on the electro-optical responses of chiro-birefringent substances are discussed.
