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 ...

The researchers prepared a Be⁺-HD⁺ two-component ion Coulomb crystal at millikelvin temperatures in a linear ion trap. They developed an innovative quantum state preparation and spatially resolved ...

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 ...

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 ...

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 ...
