The rare earth electronic transitions, widely exploited for optical applications, occur within the shielded 4f shell and originate very sharp absorption (or emission) lines in spectra of crystals measured at low temperatures. This work covers a spectral region as wide as 75-25000 cm-1 at a resolution as fine as 0.01 cm-1.
