Monolithic superconducting emitter of tunable circularly polarized terahertz radiation [PDF]

, 2017
We propose an approach to control the polarization of terahertz (THz) radiation from intrinsic Josephson-junction stacks in single crystalline high-temperature superconductor $Bi_2Sr_2CaCu_2O_{8+\delta}$. By monolithically controlling the surface current

Structure elucidation of \(\textit {in situ}\) generated chiral hypervalent iodine complexes via vibrational circular dichroism (VCD)

, 2022
The structure of \(\textit {in situ}\) generated chiral aryl-\(\gamma^{3}\)-iodanes obtained under oxidative reaction conditions was not yet observable with experimental techniques and their proposed structures are purely based on DFT calculations. Herein, we establish vibrational circular dichroism (VCD) spectroscopy as an experimental technique to ...

VCD helps others in molecular aggregates [PDF]

, 2019
Molecular self-assembly is the driving force of a great number of physical, chemical and biological processes in Nature.1 The properties of the molecular aggregates are markedly dependent on the intermolecular forces which hold together the building ...

Enantioselective Total Synthesis of (–)-Myrifabral A and B [PDF]

, 2020
A catalytic enantioselective approach to the Myrioneuron alkaloids (−)-myrifabral A and (−)-myrifabral B is described. The synthesis was enabled by a palladium-catalyzed enantioselective allylic alkylation, that generates the C(10) all-carbon quaternary ...

Explicit factorization of external coordinates in constrained Statistical Mechanics models [PDF]

, 2006
If a macromolecule is described by curvilinear coordinates or rigid constraints are imposed, the equilibrium probability density that must be sampled in Monte Carlo simulations includes the determinants of different mass-metric tensors.

Phytotoxic Activity of Metabolites Isolated from Rutstroemia sp.n., the Causal Agent of Bleach Blonde Syndrome on Cheatgrass (Bromus tectorum)

Molecules, 2018
A fungal pathogen soon to be described as Rutstroemia capillus-albis (Rutstroemiaceae, Helotiales, Leotiomycetes) has been identified as the causal agent of ‘bleach blonde syndrome’ on the invasive annual grass weed Bromus tectorum ...

A Stern-Gerlach separator of chiral enantiomers based on the Casimir-Polder potential

, 2018
We propose a method to separate enantiomers using parity violation in the Casimir-Polder potential between chiral mirrors and chiral molecules. The proposed setup involves a molecular beam composed of chiral molecules passing through a planar cavity ...

Fourier transform spectroscopy in the vibrational fingerprint region with a birefringent interferometer [PDF]

, 2017
We introduce a birefringent interferometer for Fourier transform (FT) spectroscopy in the mid-infrared, covering the vibrational fingerprint region (5-10 μm, 1000-2000 cm-1), which is crucial for molecular identification.

A vibrational circular dichroism (VCD) methodology for the measurement of enantiomeric excess in chiral compounds in the solid phase and for the complementary use of NMR and VCD techniques in solution: the camphor case

The Analyst, 2018
For the first time, it is shown that VCD spectroscopy can be used to determine the % ee in chiral solid samples.

Chiral self-assembly of enantiomerically pure (4S,7R)-campho[2,3-c]pyrazole in the solid state: a vibrational circular dichroism (VCD) and computational study

Tetrahedron: Asymmetry, 2014
NH-Indazoles in solid phase usually form NHN hydrogen bonds between positions 1 and 2, which determine the secondary structure, forming dimers, trimers, or catemers (chains). Thus, the difficulty of the experimental analysis of the structure of the family of 1H-indazoles is clear.
