Protonated methane, a.k.a. CH5+, is a highly unusual molecule that scientists and astronomers suspect may be found within the interstellar medium where stars and planets are formed. To identify ...

Pharmaceutical manufacturers face significant challenges when analyzing low-volatility Class 2 residual solvents, as conventional static headspace gas chromatography methods struggle with these ...

Microwave spectroscopy, interfaced with quantum chemical calculations, has emerged as a pivotal technique for elucidating the detailed structural and dynamical properties of molecules. This ...

Controlling electronic 1 and/or nuclear 2,3 motion in molecules using external fields represents, at the moment, the ‘holy grail’ of chemistry. More than half a century ago, the 1966 Nobel Prize ...

A new spectroscopy technique reveals that pairs of gaseous water molecules form short-lived complexes (Proc. Natl. Acad. Sci. U.S.A. 2021, DOI: 10.1073/pnas.2020941118). “You might think, come on, ...

Infrared spectroscopy is a standard technique, which depends upon the interaction between infrared radiation and the vibrating dipole moments of molecules. Except for homonuclear diatomics and noble ...
