Criegee intermediates meet rotational spectroscopy

, 2020
Carbonyl oxides, R1R2COO, alternatively known as Criegee intermediates (CIs), are short-lived molecules produced from ozonolysis of alkenes. These ozonolysis reactions yield highly excited CIs, and most of them promptly decay with emission of the OH ...

Rotational spectroscopy

2016
This chapter derives expressions for the rotational energy levels of diatomic and polyatomic molecules. It shows how to interpret rotational spectra, in which only the rotational state of a molecule changes. It also emphasizes how rotational spectroscopy provides very precise details of bond lengths and bond angles of molecules in the gas phase.

Methylsalicylate:  A Rotational Spectroscopy Study

The Journal of Physical Chemistry A, 2007
We report the free-jet rotational spectra of methylsalicylate, a molecule with a possible tautomeric and conformational equilibrium. In the ground electronic state, the molecule adopts a form stabilized by an intramolecular hydrogen bond between the phenolic hydrogen and the carbonylic oxygen, and this structure is characterized as the lowest-energy ...

Rotational spectroscopy of the two higher energy conformers of 2-cyanobutane

Journal of Molecular Spectroscopy, 2019
We present high-resolution rotational spectroscopy of the two higher energy conformers of 2-cyanobutane (C4H9CN). We analysed spectra starting from 12 to 27 GHz using the Cologne chirped-pulse (CP) Fourier transform microwave spectrometer, which we ...

Double resonance rotational spectroscopy of He-HCO.

Physical Chemistry, Chemical Physics - PCCP, 2019
The ground state of He-HCO+ is investigated using a recently developed double resonance technique, consisting of a rotational transition followed by a vibrational transition into a dissociative state.

Vibration-Rotation Spectroscopy

Annual Review of Physical Chemistry, 1956
Approximately four hundred titles pertaining to the topic of vibration­ rotation spectra appeared during the calendar year 1955 among the contents of the forty-three periodicals that we attempted to survey. Merely to list this bibliography without comment, in the conventional style, would con­ sume more than half of the printed pages assigned to this ...

Double Resonance Rotational Spectroscopy of Weakly Bound Ionic Complexes: The Case of Floppy CH_{3}^{+}-He.

Physical Review Letters, 2018
A novel rotational spectroscopy method applicable to ions stored in cold traps is presented. In a double resonance scheme, rotational excitation is followed by vibrational excitation into a dissociative resonance.

Rotational spectroscopy meets theory

Physical Chemistry Chemical Physics, 2013
Rotational spectroscopy is known to be a technique that is widely used to infer information on molecular structure and dynamics. In the last few decades, its role in the field of atmospheric and astrophysical investigations has rapidly grown. However, several are the challenging aspects in rotational spectroscopy, since the detection and analysis of ...
