High-Resolution Fourier-Transform Spectroscopy in Solid State Physics

Fine Isotopic Structure on Hyperfine Structure in the Monoisotopic Dopant-Ion Spectra in Crystals*

“…One of them is the RE nuclear HFS due to the interaction between the electronic core and the nucleus of an atom. [17] The IR active magnetic dipole transition lines corresponding to the transitions between low-lying Stark multiplet components are in these crystals very sharp (around 0.001 cm À1 ). 2).…”
