We use both chirped-pulse Fourier transform and frequency-modulated absorption spectroscopy to study the rotational spectrum of 2-methoxyethanol (CH _3 OCH _2 CH _2 OH) in several frequency regions ranging from 8.7 to 500 GHz. The resulting rotationa

The chemistry of the interstellar medium occurs under extreme conditions and can lead to the formation of exotic molecules. These are species that on Earth are unstable and/or highly reactive. Their discovery in space is usually based on the astronom

Spectral line observations encode a wealth of information. A key challenge, therefore, lies in the interpretation of these observations in terms of models to derive the physical and chemical properties of the astronomical environments from which they

This work aims to spectroscopically characterize and provide for the first time direct experimental frequencies of the ground vibrational state and two excited states of the simplest alkynyl thiocyanate (HCCSCN) for astrophysical use. Both microwave

ZrO is a well-studied metal monoxide because of its astrophysical importance in characterizing S stars. The bands of the d ^3 Φ–a ^3 Δ system ( γ system) with ${v}^{{\prime} }\leqslant 4$ and v ″ ≤ 5 are rotationally analyzed using the PGOPH

YO bands are conspicuous in the spectra of S stars. The laboratory spectrum of the A ^2 Π–X ^2 Σ ^+ electronic transition has been recorded with a Fourier transform spectrometer using a composite-wall hollow cathode lamp source. The A ^2 Π–X ^

New highly exothermic formation pathways incorporating both thermodynamic and kinetic control for the newly astronomically detected H _2 CNCN molecule are paired with extremely accurate quantum chemical rovibrational spectroscopic computations. The r

Seven rotational and fine-structure transitions of the deuterated molecular ion SD ^+ in the X ^3 Σ ^− ground electronic state have been measured in the 271–863 GHz region in the laboratory. This ion has been produced by direct-current glow disc
