Abstract
The vibronic absorption spectra of praseodymium, neodymium, and erbium ethylsulfate were used to construct tentative vibrational energy-level diagrams for the crystals. With this technique, 42 levels ranging from 18 to 360 cm—1 were identified. The energy-level spectra were used to calculate the specific heat of the crystals from 0° to 15°K as an additional check on the origin of the observed absorption spectra and fair to good agreement with measured specific heats was achieved.
