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 present mass-correlated rotational alignment spectroscopy, based on the optical excitation of a coherent rotational quantum wave and the observation of temporal wave interferences in a mass ...

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, ...

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

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 ...

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

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 ...

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 ...
