Understanding the Changes in the Circular Dichroism of Light Harvesting Complex II upon Varying Its Pigment Composition and Organization [PDF]

open access: yes, 2007
In this work we modeled the circular dichroism (CD) spectrum of LHCII, the main light harvesting antenna of photosystem II of higher plants. Excitonic calculations are performed for a monomeric subunit, taken from the crystal structure of trimeric LHCII ...

Eradicating Backscattering through Circular Conversion Dichroism in Optical Regime

open access: yes, 2023
Circular dichroism (CD) and asymmetric transmission (AT) are two outstanding chiroptical effects, which can be produced by planar chiral devices due to their distinct response to oppositely handed input light.

Magnetic circular dichroism versus orbital magnetization

open access: yesPhysical Review Research, 2020
The magnetic circular dichroism sum rule yields an extremely useful ground-state observable, which provides a quantitative measure of spontaneous time-reversal symmetry breaking (T-breaking) in a given material.

Protein fiber linear dichroism for structure determination and kinetics in a low-volume, low-wavelength couette flow cell [PDF]

open access: yes, 2004
High-resolution structure determination of soluble globular proteins relies heavily on x-ray crystallography techniques. Such an approach is often ineffective for investigations into the structure of fibrous proteins as these proteins generally do not ...

Electrically controlled terahertz magneto-optical phenomena in continuous and patterned graphene

open access: yesNature Communications, 2017
Time reversal symmetry breaking gives rise to magnetic circular dichroism and Faraday rotation in graphene. The authors use terahertz magneto-electro-optical spectroscopy to demonstrate that electrostatic doping at a fixed magnetic field allows inversion

Dual-Retarder Mueller Polarimetry System for Extraction of Optical Properties of Serum Albumin Protein Media

open access: yesSensors, 2021
A dual liquid-crystal variable retarder Mueller polarimetry system incorporating a gold-based surface plasmon resonance prism coupler was proposed for extracting the optical properties of serum albumin protein media in the reflectance configuration.

DichroMatch: a website for similarity searching of circular dichroism spectra

open access: yes, 2012
Circular dichroism (CD) spectroscopy is a widely used method for examining the structure, folding and conformational changes of proteins. A new online CD analysis server (DichroMatch) has been developed for identifying proteins with similar spectral ...
