High-Resolution Infrared Spectroscopy and ASAP Analysis of Cyclopentadiene: The Vibrational Modes below 860 cm and the Mode at 961 cm
Luis Bonah, Marie-Aline Martin-Drumel, Olivier Pirali +9
The spectroscopic fingerprints of vibrationally excited states of astronomical molecules are interesting for multiple reasons. They are excellent temperature probes of the correspo…

Evidence for electron spin-torsion coupling in the rotational spectrum of the CHCO radical
Laurent H. Coudert, Olivier Pirali, Marie-Aline Martin-Drumel +4
Open-shell non-rigid molecular systems exhibiting an internal rotation are likely candidates for a coupling between the spin angular momentum of the unpaired electron and the torsi…

Submillimeter-wave spectroscopy of the CHO radical
Jean-Thibaut Spaniol, Olivia Chitarra, Olivier Pirali +2
The methoxy radical, CHO, has long been studied experimentally and theoretically by spectroscopists because it displays a weak Jahn-Teller effect in its electronic ground state…
