Figure 11.13 shows the energy levels involved and the transitions studied for H2 in the N = 1 rotational level of the G 1 + state. The experiments were performed using a fixed microwave frequency, typically 9204 MHz, and the resonances detected by scanning the magnetic field amplitude modulation of the microwave power at 100 kHz and lock-in amplifier detection were employed. Polarising filters were used to detect the fluorescence, so that changes in polarisation could be observed. 

We can call the terms shown explicitly in Equation (A3) quadratic terms other (higher-order) terms can exist [Ref. 7, Section 6.7]. The above spin-Hamiltonian is used to obtain the energies (and hence also transition energies) of the spin system considered. Another, similar spin-Hamiltonian (with the excitation magnetic-field amplitude vector B, replacing B in Equation (A3)), yields the transition relative intensities. The line positions and intensities obtained are expressed in terms of the scalar ( tensors of zeroth rank) parameters g, gn, D, P,A,..., derived as projections from the matrices g, gn, D, P and A.12...

The harmonic content of undulator emission increases with magnetic field amplitude. The form of the spectrum depends on K, which is independent of the electron energy (19) and on the parameter I, which takes into account the angular spread of the electron (o ) and the acceptance angle of the detector (Q) ... 

In case of Zeeman sublevels or hfs levels, the allowed RF transitions are magnetic dipole transitions. Optimum conditions are then achieved if the sample is placed at the maximum of the magnetic field amplitude of the RF field. This can be realized, for instance, inside a coil that is fed by an RF current. For electric dipole transitions (for example, between Stark components in an external dc electric field) the electric amplitude of the RF field should be maximum in the optical pumping region.
