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.

The group then measured and analyzed the rotational spectrum of 2-methoxyethanol on Earth, which Fried described as "the unique patterns of light they give off as they tumble end-over-end in space." ...

Fried began by measuring the rotational spectrum of 2-methoxyethanol samples in the lab; he recorded a total of 2,172 possible energy signals for the molecule.

Promising rotational spectra 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 ...

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.

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 ...

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 ...
