The electric dipole moment of NO [ital A] [sup 2][Sigma][sup +] [ital v][prime]=0 measured using Stark quantum-beat spectroscopy
- Combustion Research Facility, Sandia National Laboratories, Livermore, California 94551-0969 (United States)
We report measurements and analysis of Stark quantum beats observed in the fluorescence of nitric oxide (NO) from which we determine the electric dipole moment of the [ital A] [sup 2][Sigma][sup +] [ital v][prime]=0 state. A pulse-amplified cw dye laser was used to excite the [ital A]--[ital X] (0,0) [ital Q][sub 1](1) transition of [sup 14]N[sup 16]O in electric fields up to 22.5 kV/cm. Fourier analysis of the time-resolved laser-induced fluorescence signals yielded Stark tunings for each of the six [vert bar][ital M][sub [ital F]][vert bar] hyperfine sublevels in the [ital N]=1, [ital J]=3/2 spin-rotational level. The measurements were fit to a model Hamiltonian including fine, hyperfine, and Stark matrix elements. The resulting dipole moment was then corrected for polarizability effects to yield a value for the [ital A] [sup 2][Sigma][sup +] [ital v][prime]=0 state of [mu][sub [ital A]]=1.08[plus minus]0.04 D. This result compares favorably to a previous measurement of [mu][sub [ital A]] in [ital v][prime]=3 and to our quantum theoretical calculations of the [ital A] [sup 2][Sigma][sup +] [ital v][prime]=0 state reported here.
