Interaction of a supersonic NO beam with a static and a resonant RF field: Measurement of rotationally resolved dipole moments

The attenuation spectra of a molecular NO beam is measured by its interaction with a resonant RF field. The figure shows the Stark field dependence of the resonant frequency of the oscillating field for the three cases corresponding to distinct J values as indicated. Notice the clear linear dependence from which a value of the dipole moment was deduced.
