The conformational equilibrium of the general anesthetic propofol (2,6-diisopropylphenol) has been studied in a supersonic expansion using broadband chirped-pulse microwave spectroscopy. Three conformers originated by combined internal rotation hydroxyl and two isopropyl groups have detected jet-cooled rotational spectrum. most stable conformer exhibits tunneling splittings associated with group, from which we determined torsional potential barrier heights (905−940 cm−1). carbon backbone...
The microwave spectrum of the mono-fluoro-benzoic acids, 2-fluoro-, 3-fluoro-, and 4-fluoro-benzoic acid have been measured in frequency range 4-14 GHz using a pulsed beam Fourier transform spectrometer. Measured rotational transition lines were assigned fit rigid rotor Hamiltonian. Assignments made for 3 conformers 2-fluorobenzoic acid, 2 3-fluorobenzoic 1 conformer 4-fluorobenzoic acid. Additionally, gas phase homodimer was detected, spectra showed evidence proton tunneling. Experimental...
The rotational spectra of five isotopologues the 1:1 complex trifluoroanisole–water have been investigated with pulsed jet Fourier transform microwave spectroscopy. triple fluorination methyl group greatly affects features spectrum water, respect to those related anisole–water. shape, internal dynamics, and isotopic effects turned out be quite different from anisole–water adduct (Giuliano, B. M.; Caminati, W. Angew. Chem., Int. Ed. 2005, 44, 603−606). However, as in anisole–water, water has...
Eight isotopologues of HGeBr and nine DGeBr have been studied in natural abundance by pulsed-jet Fourier transform microwave spectroscopy. The reactive germylene species were produced an electric discharge at the exit a pulsed molecular beam valve using precursor mixtures H3GeBr or D3GeBr high pressure neon. In 5–25GHz operating range spectrometer, only a-type transitions observed; K=0 for 1 DGeBr. From observed transitions, improved geometry has determined nuclear quadruple constants Ge Br...
Four fluoromethyl polyynes, 5,5,5-trifluoro-1,3-pentadiyne, CF3C⋮CC⋮CH, 7,7,7-trifluoro-1,3,5-heptatriyne, CF3C⋮CC⋮CC⋮CH, 1,5,5,5-tetrafluoro-1,3-pentadiyne, CF3C⋮CC⋮CF, and 4,4,4-trifluoro-1-nitrile-2-butyne, CF3C⋮CC⋮N, were studied by pulsed-jet Fabry Perot Fourier transform microwave spectroscopy. The molecules produced pulsed high voltage discharges of dilute mixtures precursor gases such as trifluoropropyne in an argon carrier jet. carbon-13 deuterium substituted isotopomers...
The rotational spectrum of the 1,1-difluoroprop-2-ynyl radical, F2Ċ–CCH, a partially fluorinated variant propargyl has been recorded in ground electronic, B12, state using pulsed discharge, pulsed-jet, Fabry-Pérot Fourier transform microwave spectroscopy. Five successive a-type transitions, from N=1-0 to N=5-4, and Ka=0, 1, 2, were measured between 6.5 32.5GHz with an uncertainty 5kHz. molecular constants, including fine hyperfine precisely determined. These constants are compared our...
The rotational spectra of T-shaped cyanoacetylene carbon dioxide complex, HCCCN -CO 2 , were measured using two Balle-Flygare type Fourier transform microwave (FTMW) spectrometers between 1.4 GHz and 22 GHz.The low J transitions recorded the frequency FTMW spectrometer at University Arizona with a state-of-theart resolution "full width half maximum" (FWHM) 1 kHz.The above 4 Wesleyan University.Spectral hyperfine structures due to 14 N nuclear quadrupole coupling interactions can be fully...
