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 ...

HD⁺ is the simplest heteronuclear molecular ion, composed of one proton, one deuteron, and one electron. Its vibrational-rotational transition energies can be precisely calculated, making it an ideal ...

Laser Doppler vibrometers (LDVs) measure vibrations in ways that other sensors can't. From large aircraft structures to microscopic MEMS sensors, and Laser Doppler vibrometers (LDVs) measure ...

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 ...
