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 ...

Raman spectroscopy is a type of vibrational spectroscopy that relies on Raman scattering to deduce the vibrational, rotational and other low-frequency modes of different molecules. Once 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 ...
