The electric dipole–magnetic dipole polarizability tensor κ′, introduced to interpret the optical activity of chiral molecules, has been expressed in terms of a series of density functions kαβ′, which can be integrated all over the three-dimensional space to evaluate components καβ′ and trace καα′. A computational approach to kαβ′, based on frequency-dependent electronic current densities induced by monochromatic light shining on a probe molecule, has been developed. The dependence of kαβ′ on the origin of the coordinate system has been investigated in connection with the corresponding change of καβ′. It is shown that only the trace kαα′ of the density function defined via dynamic current density evaluated using the continuous translation of the origin of the coordinate system is invariant of the origin. Accordingly, this function is recommended as a tool that is quite useful for determining the molecular domains that determine optical activity to a major extent. A series of computations on the hydrogen peroxide molecule, for a number of different HO–OH dihedral angles, is shown to provide a pictorial documentation of the proposed method.

The Impact

Photonic crystals are engineered structures able to control the propagation and properties of light. Due to this ability, they can be fashioned into optical components for advanced light manipulation and sensing. For these applications, a particularly interesting case study is the gyroid srs-network, a three-dimensional periodic network with both cubic symmetry and chirality. In this work we present the fabrication and characterization of three-dimensional cubically symmetric 8-srs photonic crystals derived from combination of eight individual gyroid srs-networks. We numerically and experimentally investigate optical properties of these photonic crystals and study in particular, the impact of cubic symmetry on transmission and optical activity (OA). Gyroid photonic crystals fabricated in this work can lead to the development of smaller, cheaper, and more efficient optical components with functionalities that go beyond the concept of lenses.

Raman Optical Activity

The core techniques of structural biology, namely X-ray crystallography and multidimensional NMR, are often not applicable to many important samples due to fundamental experimental problems, such as the lack of suitable crystals in the X-ray case or excessive size or flexibility for NMR. Carbohydrates and glycoproteins are especially challenging in this respect. The novel technique of vibrational ROA (Raman optical activity), which combines the advantages of vibrational spectroscopy with the extra sensitivity to three-dimensional structure of chiroptical methods such as CD (circular dichroism), has much promise for studying a large range of biomolecules, from the smallest to the largest, in aqueous solution. Among other things, it is capable of providing structural information about both the polypeptide and the carbohydrate structure of intact glycoproteins and should become an indispensable spectroscopy tool for glycobiology.
