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 ...

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 ...

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, ...

Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have begun to use neural networks to identify the structural signatures of molecular gases, potentially providing new ...

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 ...

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

Publications of the Astronomical Society of the Pacific, Vol. 108, No. 729 (1996 November), pp. 962-966 (5 pages) CCD spectra were obtained for the late-B and early-A type Algol binaries AI Draconis ...

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 ...
