The polarized vibronic spectra of PrCl3 and PrBr3, as well as Pr3+ in LaCl3 and LaBr3, were observed. The theory of vibronic transitions for the dilute salt is shown to predict a spectrum which closely resembles the vibronic spectrum of the pure salt

The absorption and fluorescence spectra of 1% and 10% Pr3+ in LaBr3 were observed and an analysis carried out. The energy levels of these Pr3+ ions are very similar to Pr3+ in LaCl3, except that the centers of the J levels differ on the order of 102

The electronic energy levels of ${\mathrm{U}}^{4+}$ in ZrSi${\mathrm{O}}_{4}$ have been obtained from the absorption spectra of oriented single crystals. This host was chosen because of the relatively high (${D}_{2d}$) symmetry of the ${\mathrm{Zr}}^

The crystalline field interaction was calculated using first‐order perturbation theory on intermediate coupling wave functions of Tm3+ in a D3h field. Good agreement with experimental data of Tm3+ diluted with La(C2H5SO4)3·9H2O was obtained. The f

The absorption spectrum of 0.5 mole % Nd3+ in a LaBr3 single crystal was obtained and most of the crystalline field Stark levels identified. The spectrum is very similar to that obtained from Nd3+ in LaCl3 and, in fact, the crystalline field paramete

Recent work of Wood and Kaiser has yielded vibronic data on ${\mathrm{Sm}}^{2+}$ doped in two isomorphic crystals, Sr${\mathrm{F}}_{2}$ and Ba${\mathrm{F}}_{2}$. The present work proposes a model using Born-von Karmann boundary conditions, which pred

The Advanced Sensor Evaluation and Test (ASET) facility is used to characterize infrared sensor performance under conditions simulating those of outer space (viz., low radiant back-ground and high vacuum). One function of the facility is to provide t

Off‐normal reflection spectra of thin films of CaF2, SrF2, and BaF2 deposited on a silver substrate have been obtained. They exhibit decreased reflectivity at the long wave limit of the longitudinal optical branch. The values so obtained are in agr
