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 ...

Subscribe to our newsletter for the latest sci-tech news updates. The researchers prepared a Be⁺-HD⁺ two-component ion Coulomb crystal at millikelvin temperatures in a linear ion trap. They developed ...

Quantum chemical spectroscopy for molecular dynamics integrates first-principles electronic structure methods with spectroscopic simulation to unravel the atomic-scale motions that govern chemical and ...

In the gaseous phase, vibrational-, rotational- and translational-energy transfer between small molecules can be observed experimentally from time-dependent optical spectra. Populations in the ...

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 ...

To identify molecules on Earth or in outer space, scientists typically record the spectrum of light absorbed -- each molecule has its own unique spectrum. CH5+, consists of a central carbon atom with ...

It may now be possible to begin interpreting the detailed rotational-vibrational CH5+ spectra previously recorded by other researchers, thanks to the work of a group of theoretical chemists at Queen's ...
