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 ...

Ultrafast 2D spectroscopy uses correlated multiple light−matter interactions for retrieving dynamic features that may otherwise be hidden under the linear spectrum; its extension to the terahertz ...

Pharmaceutical manufacturers face significant challenges when analyzing low-volatility Class 2 residual solvents, as conventional static headspace gas chromatography methods struggle with these ...

Faraday rotation spectroscopy (FRS) enables the detection of paramagnetic molecules by detecting changes in the polarization state of the linearly polarized light caused by a gaseous medium immersed ...

Researchers developed a new method that allows, for the first time, to elucidate the chiral structure of molecules -- the exact spatial arrangement of the atoms -- by nuclear magnetic resonance (NMR) ...

Raman spectroscopy is a form of vibrational spectroscopy that is used to observe changes in a molecule; these may be rotational, vibrational or some other form. It helps to understand the ...
