A 20‐parameter least‐squares fit to the levels of Ho3+:LaCl3 observed by Dieke and Pandey has been obtained. The results are in substantial agreement with their assignments and with the subsequent analysis of Rajnak and Krupke. A considerably mor

The emission spectrum of the First Negative Group of ionized molecular nitrogen ( N 2 + 1 NG : B 2 Σ u + → X 2 Σ g + ) has been photographed at high resolution in the spectral region from 3800 to 4750 A. Lines have been identified as arising from

New measurements of the optical spectrum of trivalent neodymium in a hexagonal lanthanum chloride host have been made at 4 and 77 K at wavelengths down to 2500 A (40 000 cm−1). Crystal quantum number assignments for new energy levels were derived f

We qualitatively describe magnetic structures in both π- and σ -polarization for In(I) Rydberg series. Two types of shift of Zeeman patterns, proportional to the square of the magnetic field, and ascribable respectively to partial Paschen-Back effe

A diagonalization of the matrices representing the combined atomic and crystal‐field interactions for the 4f4 configuration has provided the basis for interpreting the spectrum of Pm3+:LaCl3. Experimental data were drawn from the literature and wer

The A2Σ+ → X2Π band system of OT was observed for the first time. Fourteen bands with 0 ≤ v′ ≤ 4 and 0 ≤ v″ ≤ 3 were photographed at high resolution and rotationally assigned. Fitted values of 18 effective parameters of the model Hami

The laser-rf double-resonance technique has been used to study the hyperfine structure (hfs) of the excited $3{d}^{4}4s^{4}D$ levels of $^{15}\mathrm{V}$ in a continuation of earlier atomic-beam magnetic-resonance studies of the lower levels. The new

The polarized absorption and fluorescence spectra of 0.01–5% Np3+ doped into single‐crystal LaCl3 were measured at moderate and high resolution in the range to 50 000 cm−1 at 298, 77, and 4 K. The 150 crystal field components identified were fi

The spectrum of U3+:LaCl3 has been analyzed; 53 crystal states of electronic origin have been identified, many of them accompanied by extensive vibronic sidebands having a recognizable structure similar to that for lanthanide‐doped LaCl3. Seventeen

Fluorescent, excitation, and absorption spectra of DyF3 are reported. The energies of the electronic states of the ground level are significantly shifted compared to those of the dilute system DyxLa1−xF3 and are consistent with recent specific heat
