We demonstrate the application of molecular rotational spectroscopy to measure the conformation isomerization rate of vibrationally excited pent-1-en-4-yne (pentenyne). The rotational spectra of ...

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 ...

Using muon spin rotation spectroscopy, researchers from Japan and Canada successfully captured the rapid conversion of an ...

THE absorption spectra of polyatomic molecules are usually so complicated that an analysis of their rotational fine structure seems impossible. We have therefore tried if the magnetic rotation spectra ...

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, ...

What does it take to transform a tried and tested, but somewhat forgotten, “old-school” spectroscopy technology into something that scientists see as the next big thing in molecular structural ...

The use of T-rays, or terahertz radiation, to identify substances by their spectroscopic fingerprints is a rapidly moving field. The dominant approach is presently terahertz time-domain spectroscopy.

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 ...
