Analysing Vibrational Circular Dichroism: Confidence Levels for Absolute Chirality Assignment
The application of chiroptical methods such as vibrational circular dichroism (VCD) spectroscopy is valuable in the assignment of absolute chirality. Assignment of chirality traditionally involves visual comparison of calculated and experimental spectra which can be subjective and time consuming. …

Development of methodology to assign absolute configurations using vibrational circular dichroism
De kennis van de 3D structuur van actieve bestanddelen van chirale medicijnen is zeer belangrijk, aangezien stereo-isomeren dikwijls een verschillende activiteit vertonen. Er zijn meerdere technieken beschikbaar om deze Absolute Configuratie te bepalen (eenkristal x-straal diffractie bijv.). Een …

A critical assessment of possible pitfalls in absolute configuration assignment using Vibrational Circular Dichroism
Vibrational Circular Dichroism (VCD) is no longuer a curious novelty in the field of molecular spectroscopy as VCD spectrometers are commercially available as well as the algorithms to calculate the spectra, which are implemented in various software packages. This makes VCD routinely applicable for …

Finite-Difference and Analytic-Gradient Approaches for Simulating Vibrational Circular Dichroism Using Second-Order Møller-Plesset Perturbation Theory and Configuration Interaction
Vibrational circular dichroism (VCD) is defined as the differential absorption of left- and right-circularly polarized light in the infrared region of the electromagnetic spectrum. Application of this spectroscopy is primarily directed towards the elucidation of molecular absolute configuration. As …

Advanced Quantum Mechanical Simulations of Circular Dichroism Spectra
… to predict optical rotations and electronic circular dichroism for naturally occurring antiplasmodial and anticancer drug candidates. We find that by comparing the computational results directly with those obtained through experimental measurement, we can provide reliable absolute config- …
