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 ...

We present mass-correlated rotational alignment spectroscopy, based on the optical excitation of a coherent rotational quantum wave and the observation of temporal wave interferences in a mass ...

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 ...

Controlling electronic 1 and/or nuclear 2,3 motion in molecules using external fields represents, at the moment, the ‘holy grail’ of chemistry. More than half a century ago, the 1966 Nobel Prize ...

Microwave spectroscopy, interfaced with quantum chemical calculations, has emerged as a pivotal technique for elucidating the detailed structural and dynamical properties of molecules. This ...

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 ...

The film discusses infrared spectroscopy, a powerful analytical tool that utilizes infrared radiation to analyze chemical compounds. It explains the nature of electromagnetic radiation and how ...
