As part of a program to determine how small structural changes become manifest in the optical properties of crystals we used classical dipole–dipole interaction calculations to estimate the linear birefringence and optical rotatory power of the crystals Ph4X where X ~ C, Si, Ge, Sn, and Pb. Field induced effects including second harmonic generation, the electro-optic response and electrogyratio...

The optical rotatory dispersion behavior of the oxidized, reduced, and carbon monoxide-reduced forms of cytochrome c’ from Rhodopseudomonas palustris and cytochrome cc’ from Chromatium strain D, Rhodospirillum rubrum, and Pseudomonas dinitrificans, was studied in the range from 600 to 185 nm. These cytochromes exhibited an apparent positive Cotton effect in the Soret region characteristically d...

Graphene can be magnetized through nonlinear response of its orbital angular momentum to an intense circularly polarized light. This optomagnetic effect well exemplified by the Inverse Faraday Effect (IFE) where optically-generated DC magnetization leads graphene's optical activity. We provide a single-particle quantum mechanical model IFE in graphene solving Schr\"odinger's equation presence r...

Partial Rotatory Powers.-Recent experimental data on the circular dichroism spectra of a planar, cyclic, model compound, L-5-methyl pyrrolid-2-one," 2 and on the vacuum ultraviolet-absorption spectra of poly-L-alanine,3 as well as recent theoretical work on the spectra of simple amides4 and polypeptides,5 indicate that there is much to be clarified before a truly satisfactory theory of optical ...

1. The association and ionization constants of copper(I1) complexes of glycylglycylglycylglycine, L-alanylglycylglycylglycine, glycylglycylglycylglycylglycine, L-alanylglycylglycylglycylglycine, glycylglycylglycylglycyl-L-alanine, L-valyl-Lleucyl-L-seryl-L-glutamylglycine, and L-valyl-L-leucyl-Lseryl-L-glutaminylglycine were computed from potentiometric measurements. The acid ionization constan...

Three dimensional helical chiral metamaterials resulted in effective manipulation of circularly polarized light in the visible infrared for advanced nanophotonics. Their potentialities are severely limited by the lack of full rotational symmetry preventing broadband operation, high signal-to-noise ratio and inducing high optical activity sensitivity to structure orientation. Complex intertwined...
