Spectroscopic detection of gas-phase HOSO2

Publikováno v: Physical Chemistry Chemical Physics. 23:25063-25069

The HOSO2 radical was detected by microwave spectroscopy in a discharge plasma of a SO2/H2O gas mixture. The observed spectrum shows tunneling splittings due to the OH torsional motion. A least-squares analysis considering interactions between the tw

Criegee intermediates meet rotational spectroscopy

Autor: Yasuki Endo, Masakazu Nakajima, Carlos Cabezas

Publikováno v: International Reviews in Physical Chemistry. 39:351-384

34 pags., 15 figs., 3 tabs.
Carbonyl oxides, RRCOO, 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

Pure rotational spectrum of HCI

Autor: Yasuki Endo, Masakazu Nakajima

Publikováno v: Journal of Molecular Spectroscopy. 362:25-28

The 101–000 and 202–101 rotational transitions of a monohalomethylene, HCI, are observed in a discharge plasma of diiodomethane by Fourier-transform microwave (FTMW) and FTMW-microwave double-resonance spectroscopy. The effective rotational const

Pure rotational spectrum of cis-OSOO

Autor: Yasuki Endo, Masakazu Nakajima

Publikováno v: Chemical Physics Letters. 725:14-17

Pure rotational transitions of cis-OSOO are identified in a discharge plasma of a SO2 and O2 gaseous mixture by Fourier-transform microwave (FTMW) and FTMW-MW double-resonance spectroscopy. Both a- and b-type transitions are observed for this molecul

A further investigation of the A1Πu state of dicarbon

Autor: Masakazu Nakajima

Publikováno v: Journal of Molecular Spectroscopy. 355:14-18

Doppler-limited absorption spectra of dicarbon are recorded for Phillips bands ( A 1 Π u – X 1 Σ g + ) involving v ′ = 9 –11 at a room temperature. Small energy shifts of rotational levels are identified in the v = 10 level of the A 1 Π u st

Hyperfine analysis of the microwave spectrum of the vinylthio radical, CH2CHS

Autor: Yasuki Endo, Masakazu Nakajima, Yoshihiro Sumiyoshi, Takanobu Tokumasu

Publikováno v: Journal of Molecular Spectroscopy. 353:20-22

Measurement of pure rotational transitions for the vinylthio radical, CH2CHS, previously observed by Fourier-transform microwave spectroscopy (Nakajima et al., 2007), are extended to a number of fine and hyperfine component lines split by the unpaire
