Electronic circular dichroism behavior of chiral Phthiobuzone

Coupled plasmons induce broadband circular dichroism in patternable films of silver nanoparticles with chiral ligands.

This contribution reports the chiro-optic response of as-cast and photopatterned films of silver nanoparticles capped with photothermally-cleavable chiral ligands. We demonstrate broadband circular dichroism in these nanoparticle films, which is not present in dispersions of the nanoparticles capped with the chiral ligands. Long wavelength circular dichroism is derived from coupling of the plas...

A complex-polarization-propagator protocol for magneto-chiral axial dichroism and birefringence dispersion.

A computational protocol for magneto-chiral dichroism and magneto-chiral birefringence dispersion is presented within the framework of damped response theory, also known as complex polarization propagator theory, at the level of time-dependent Hartree-Fock and time-dependent density functional theory. Magneto-chiral dichroism and magneto-chiral birefringence spectra in the (resonant) frequency ...

Assignment of absolute stereostructures through quantum mechanics electronic and vibrational circular dichroism calculations.

Elucidation of absolute configuration of chiral molecules including structurally complex natural products remains a challenging problem in organic chemistry. A reliable method for assigning the absolute stereostructure is to combine the experimental circular dichroism (CD) techniques such as electronic and vibrational CD (ECD and VCD), with quantum mechanics (QM) ECD and VCD calculations. The t...

EMCD - Magnetic Chiral Dichroism in the Electron Microscope

The discovery of energy loss magnetic chiral dichroism (EMCD) has created a new approach to element specific magnetic measurements with highest spatial resolution [1]. EMCD, which is detected in the fine structure of energy loss spectra in a transmission electron microscope (TEM) probes the same electronic transitions as its well established X-ray counterpart, the X-ray magnetic circular dichro...
