Static discharges transitional

An important extension of the measurements was the application of a static electric field, applied between the Stark plates, and the consequent observation of Stark components in the double resonance lines, from which the electric dipole moment could be determined. An example of the spectra obtained is shown in figure 11.7(b). In their later work Field and Bergeman [12] replaced the manganese atomic emission line with white light from a CS molecular discharge lamp and they were then able to study the A-doublet transitions in rotational levels J — 1 to 9 of the A 1 n state.
