So they collected a rotational spectrum of the gas-phase molecule in the lab, says Gabi Wenzel, a postdoctoral researcher in McGuire’s lab. It was no easy task.

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

Much more promising are the rotational spectra of dimers and monomers, which calculations suggest should be much more distinct than infrared spectra. These features appear in the extremely ...

It may now be possible to begin interpreting the detailed rotational-vibrational CH5+ spectra previously recorded by other researchers, thanks to the work of a group of theoretical chemists at ...

American Institute of Physics. "Closing in on the elusive rotational-vibrational CH5+ spectra." ScienceDaily. ScienceDaily, 24 May 2016. <www.sciencedaily.com / releases / 2016 / 05 / 160524121536 ...

Their spectrum achieved rotational resolution, but the vibrational part of the spectrum was incomplete. It covered only part of CH 5+ 's C­H stretching band, from about 2,800 to 3,100 cm -1.

PURE rotation spectra of gaseous ozone have been recorded in the laboratory for the wave-length range 125–500µ. This extends the region observed by Danti and Lord (125–200µ) to longer ...
