Molecular spectroscopy and chirality

Molecular spectroscopy and chirality is a research topic within Spectroscopy. Science Explorer counts 43k research works in it since 1950. 9.9% of them reached the world's top 10% most cited for their field and year.

This cluster of papers focuses on the application of chiroptical spectroscopic methods, such as vibrational circular dichroism and optical rotation, combined with computational techniques like density functional theory and NMR, for the determination of absolute configuration, conformational analysis, and stereochemistry in organic compounds, particularly natural products. The cluster also explores the role of chiroptical spectroscopy in structure elucidation and its use in studying the chiral properties of molecules.
