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

We present a study of salicylic acid and its hydrates, with up to four water molecules, done by employing chirped-pulse Fourier transform microwave spectroscopy. We employed the spectral data set of the parent, 13C, and 2H isotopologues to determine

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

The use of CMOS sensors for rotational spectroscopy is a promising, but challenging avenue for low-cost gas sensing and molecular identification. A main challenge in this approach is that practical CMOS spectroscopy samples contain various different

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

The molecular structure of a van der Waals-bonded complex involving 2,6-di-tert-butylphenol and a single argon atom has been determined through rotational spectroscopy. The experimentally derived structural parameters were compared to the outcomes of
