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 led by Prof. GAO Xiaoming at the Anhui Institute of Optics and Fine Mechanics (AIOFM), Hefei Institutes of Physical Science (HFIPS) of Chinese Academy of Sciences (CAS) recently ...

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 ...

A new spectroscopy technique reveals that pairs of gaseous water molecules form short-lived complexes (Proc. Natl. Acad. Sci. U.S.A. 2021, DOI: 10.1073/pnas.2020941118). “You might think, come on, ...

Astronomical measurements of motion frequently utilize the Doppler effect, observing shifts in wavelength (or frequency) of emitted waves from moving sources, analogous to a changing siren pitch.
