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 ...

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 ...

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 ...

A research team from the Innovation Academy for Precision Measurement Science and Technology (APM) of the Chinese Academy of Sciences has made significant progress in precisely measuring the ...

Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences, Vol. 313, No. 1513 (Oct. 21, 1969), pp. 149-167 (19 pages) Model theoretical calculations have been made of ...

Raman spectroscopy is a type of molecular spectroscopy that involves the dispersion of electromagnetic radiation by molecules or atoms. It measures the rotational, vibrational, and other low-frequency ...

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 ...
