Electric and magnetic properties of carbon monoxide by molecular-beam electric-resonance spectroscopy
The molecular-beam electric-resonance method was used to investigate the Stark-Zeeman spectra of the J = 1, v = 0 state of CO. Along with the most abundant species 12C 16O we studied the 13C 16O and 12C 18O molecules. The electric dipole moment, the magnetic gJ factor, the magneitc susceptibility anisotropy, and the spin-rotation constant of carbon-13 were obtained. The experimental results were used to determine the polarity of the electronic charge distribution (C -O + was found), the vibrational dpendence of the electric dipole moment, and the molecular quadrupole moment.
