The National Institute of Standards and Technology (NIST) has updated its database of chemical fingerprints, called mass spectra, that are used to identify unknown chemical compounds. The NIST Mass ...

Scientists from the laboratory of Dr. Tomáš Pluskal at IOCB Prague are helping colleagues around the world identify previously unknown compounds. They have created an extensive library called MS n Lib ...

THIS is the first of a series of volumes which are intended to facilitate the identification of organic substances. The scheme commonly, though not invariably, adopted by organic chemists in this ...

This module has been designed to introduce second-year organic chemistry students to the concepts of stereochemistry through the lens of the World Health Organization’s Model List of Essential ...

Gas chromatography (GC) is used for the analytical separation of volatile substances in the gaseous phase. This chromatographic technique is widely used in various fields of research and industrial ...

Russian researchers have explained why scientists studying crude oil and celestial chemistry—as well as certain down-to-earth matters—frequently come across some molecules incorporating carbon, ...

The film discusses infrared spectroscopy, a powerful analytical tool that utilizes infrared radiation to analyze chemical compounds. It explains the nature of electromagnetic radiation and how ...
