On Optical Rotation

Sensitive optical atomic magnetometer based on nonlinear magneto-optical rotation

A self-oscillating magnetometer based on nonlinear magneto-optical rotation using amplitude-modulated pump light and unmodulated probe light (AM-NMOR) in Rb has been constructed and tested towards a goal of airborne detection of 87 magnetic anomalies. In AM-NMOR, stroboscopic optical pumping via amplitude modulation of the pump beam creates alignment of the ground electronic state of the rubidi...

Optical Vortices, Faraday Rotation, Optical Activity

Characteristic solutions to Maxwell's equations, constrained to equivalence classes by constitutive equations that have certain crystal symmetries, are represented by phase 1-forms, k, such that both 3-forms vanish: k^F = 0 and k^G = 0: Simple examples are given which show the di®erences between Faraday rotation where the 3-form of Topological Torsion is not zero, A^F 6= 0, and Optical Activity...

Optical rotation of mitochondrial membranes.

Several papers have appeared recently in which optical rotation data were used to study the structure of membranes. 1-3 The optical rotatory dispersion curves for erythrocyte membranes2 and for plasma membranes of Ehrlich ascites carcinoma1 are reported to be of the general form corresponding to an a-helix with minor but significant differences. The trough, normally found at 233 m,4 for model p...

Circular Dichroism and Optical Rotation?

Conformational Effects on the Optical Rotation of Alanine and Proline

The natural optical activity of two chiral amino acids, alanine and proline, has been calculated using HartreeFock and density-functional theory with the Becke three-parameter Lee-Yang-Parr (B3LYP) functional employing analytical response theory. The dependence of the optical activity on the molecular conformation in the gas phase was investigated. In the case of proline, calculations were also...
