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 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 ...

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 ...

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 ...

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 ...

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 ...
