Figures

Image of FIG. 1.
FIG. 1.

Part of the far-infrared LMR spectrum of the FeH radical in the level of the state. The spectrum is recorded with the laser line in parallel polarization . The pure rotational transition involved is , ; the values for the quantum number are shown by the resonances. The very obvious doublet structure is caused by lambda-type doubling; the resonances are labeled by the parity of the lower state involved in the transition. The corresponding resonances for (5.8%) and even (2.2%) can also be identified.

FIG. 2.

Part of the far-infrared LMR spectrum of the radical in the level of the state, recorded with the laser line in parallel polarization . The transition involved in the main Zeeman progression is an electric-dipole fine-structure transition, , , ; the values for involved are shown by the resonances. The corresponding resonances for can be seen at lower flux densities (marked with asterisks). The Zeeman progression at very low fields has not yet been assigned; the relative intensities of successive resonances indicate that the transition obeys the selection rule .

FIG. 3.

Diagram showing the lower energy levels of the FeH radical in the level of the state and the transitions involved in the observed far-infrared LMR spectrum. The lambda-type (parity) doubling has been exaggerated by a factor of 10 for the sake of clarity. It can be seen that the fine-structure transitions occur at much shorter wavelengths than the pure rotational transitions.

Image of FIG. 4.
FIG. 4.

A small portion of the FIR LMR spectrum of the FeH radical in the level of the state, recorded with the laser line in parallel polarization ; the complete spectrum is shown in Fig. 1. The partially resolved doublet structure on each resonance is caused by the proton hyperfine interaction. The lower field resonance is assigned to (5.8%) and the higher field resonance to (91.7%). Note the change of amplifier sensitivity between the two parts of the scan.
