M. Auzinsh et al., STUDIES OF ROTATIONAL LEVEL LAMBDA-DOUBLING BY RF-OPTICAL DOUBLE-RESONANCE SPECTROSCOPY - APPLICATION TO NAK D-1-PI, Journal of molecular structure, 410, 1997, pp. 55-58
We report here the application of optical-radio frequency double reson
ance spectroscopy for individual rotational levels of the NaK D-1 Pi s
tate. Lambda doubling constant q values for five v', J' levels are obt
ained. These data are combined with measurements of de e-f Stark-mixin
g-induced changes in optical spectra, and the electric dipole moment d
(p) in the D-1 Pi state is determined. (C) 1997 Elsevier Science B.V.
