Hyperfine structure of the Sic radical
نویسندگان
چکیده
The millimeter-wave rotational spectrum of the free 2’?SiC radical in the X 311 ground state, produced in a low-pressure glow discharge through SiH, and CO, was detected with the same reactive-molecule spectrometer used earlier to detect Sic and Si13C. Eleven rotational transitions, all but two with resolved hyperfine structure, were measured between 195 GHz (J = 4+ 5) and 372 GHz (J = 8 --+ 9). Well-resolved hyperfine splittings in the three finestructure ladders allow determination of the magnetic hyperfine constants to 2% or better.

Theoretical Structural and Spectral Analyses of TEMPO Radical Derivatives of Fullerene
The spectroscopic properties of the 2,2,6,6-tetramethyl-piperidine-1-oxyl (TEMPO) radicalderivatives of the fullerene (C60) were theoretically investigated. The ground state optimizedstructures of the radical adducts of the fullerene were calculated by using DFT (B3LYP) with 6-31G(d) level. It was concluded that a 6-6 ring junction of C60 moiety generally covalently links to thepiperidine ring ...

متن کاملFourier transform millimeter-wave spectroscopy of the ethyl radical in the electronic ground state.
The pure rotational spectrum of the ethyl radical (C2H5) has been detected for the first time with the Fourier transform millimeter-wave spectrometer. The ethyl radical is produced by discharging the C2H5I gas diluted in Ar. The 1(01)-0(00) rotational transition of the ethyl radical is observed in the frequency range from 43,680 to 43,780 MHz. The observed spectrum shows a very complicated patt...

In this study, based on Density Functional Theory (DFT), the effect of solution on the g-tensor, hyperfine coupling constant of atoms and finally the EPR spectrum of alanine free radicals induced by ionizing radiation such as electron and gamma was investigated using implicit models such as COSMO, and explicit models such as introducing hydrogen bonds to the cluster structures. The obtained res...
