Bioorganic & Medicinal Chemistry Letters, 2013 The absolute stereochemistry of chiral drugs is usually established via X-ray crystallography. However, vibrational circular dichroism (VCD) spectroscopy coupled with quantum mechanics simulations offers a rapid alternative to crystallography and is readily applied to both crystalline and non-crystalline samples. VCD is an effective complement to X-ray

Magnetic Resonance in Chemistry, Volume 63, Issue 9, Page 691-702, September 2025.This paper presents a promising analytical tool for the extraction of anisotropic 13C information (RDC and RCSA) from two oriented but immiscible lyotropic chiral domains in a single NMR sample. The methodology is based on spatially resolved 13C 1D/2D NMR experiments using the OVS approach. ABSTRACT The use of lyotropic, chiral bimesophasic systems and

Experimental and ab-initio calculated vcd spectra of the first OH-stretching overtone of (1R)-(-) and (1S)-(+)-endo-borneol [PDF]
, 2009 The near infrared (NIR) absorption and NIR-vibrational circular dichroism (NIR-VCD) spectra of dilute solutions of the two enantiomers of endo-borneol have been measured in the first OH-stretching overtone region (1600–1300 nm).

Pseudo‐Dichroism: Nanophotonic Induction of Chiroptical Activity in Symmetric Molecular Systems
Advanced Optical Materials, Volume 13, Issue 24, August 25, 2025.By analyzing vibrational circular dichroism (VCD) spectra of chiral nanomaterials, we distinguish genuine molecular chirality (true dichroism) from measurement artifacts (pseudo dichroism) using a novel, robust framework. The spectral criteria we establish apply broadly to all chiroptical techniques in nanomaterial research, enhancing precision in ...

Enantiopure Chiral Crystals: A Powerful Tool for Absolute Asymmetric Synthesis
Asian Journal of Organic Chemistry, Volume 14, Issue 8, August 2025.This review covers absolute asymmetric syntheses, which allow the preparation of enantiomerically enriched chiral compounds from achiral precursors. By exploiting the crystallization of certain compounds as a conglomerate, enantiopure chiral crystals are spontaneously obtained.
