An even closer look at the 'doubly magic' tin-100 nucleus

In a new paper published in Physical Review Letters, researchers working at CERN's ISOLDE facility describe how an upgrade to the ISOLTRAP experiment has allowed them to determine the energy necessary to bring the atomic ...

Butanol in latex paint detected by mass spectrometry technology

According to a study published in Journal of Chromatography A, using fast gas chromatography proton transfer reaction mass spectrometry (FastGC-PTR-MS) technology, a research team led by Prof. Sheng Chengyin and Associate ...

'E-nose' sniffs out mixtures of volatile organic compounds

As paint thinner, ink and adhesives dry, they can release volatile organic compounds (VOCs), which can negatively impact health. Typically, one of those VOCs is xylene, which exists as three isomers with the same elements ...

In chemistry, isomers (from Greek ἰσομερής, isomerès; isos = "equal", méros = "part") are compounds with the same molecular formula but different structural formulas. Isomers do not necessarily share similar properties, unless they also have the same functional groups. There are many different classes of isomers, like stereoisomers, enantiomers, geometrical isomers, etc. (see chart below). There are two main forms of isomerism: structural isomerism and stereoisomerism (spatial isomerism).
