Abstract Laser excitation at 206–232 nm of a supersonic free jet of Cd(CH3)2 produced an emission due to one-photon absorption from vibrationally cold A CdCH3. The 0—0 line was at 444.1 nm and ground-state vibrational frequencies of 345 cm−1 (CdCH3 stretch) and 998 cm−1 (CH3 umbrella mode) were measured. Much stronger emissions caused by multiphoton

Abstract The emission bands, first observed by R. F. Barrow, G. Drummond, and S. Walker (Proc. Phys. Soc.A67, 186–187 (1954)) in a discharge through CCl4, have been rotationally analyzed and found to be due to the A1Π-X1Σ+ transition of CCl+.

Physical Review A, 1987
The two-photon emission spectrum of a strongly driven two-level atom is defined and calculated. Such a spectrum reveals details of non-Markovian dynamics which are not observable in the usual experiments. It is shown that a clear separation of Markovian and non-Markovian regimes is possible in the two-photon emission spectrum.

Abstract The A2Σ+-X2Π system of CF has been investigated with high dispersion in the region 2190–2965 A and the rotational structure of 18 bands analyzed. Vibrational and rotational constants have been determined for levels up to v′ = 1 and v″ = 9.

Abstract The emission spectrum of B2 was reinvestigated under high resolution. Six bands of 11B2 (0-0, 1-1, 1-0, 2-1, 3-2, and 0–1) as well as four bands of 10B11B (0-0, 1-0, 2-1, and 3-2) were rotationally analysed. Accurate rotational and vibrational constants were obtained. The triplet character of the transition ( 3 Σ u − -X

The emission spectrum of 200Hg127I
Journal of Molecular Spectroscopy, 1986Abstract The ultraviolet emission systems of HgI—C → X, D → X, F3 → X, G → X, and H → X—are photographed and analyzed using tesla-discharge sources containing isotopically pure 200Hg. The previous assignment for F3 → X is revised, the main change being a decrease by 3 units in the v″ numbering.

Abstract The emission spectrum from a high frequency discharge through chlorine vapor has been reinvestigated under high resolution. Natural chlorine and the isotope 35Cl2 were used. Rotational analyses of thirty-eight bands attributed to the 35Cl2+ molecule-ion and four of the isotopic molecule (35Cl37Cl)+ have been carried out.

On the emission spectrum of HfS
Physica Scripta, 1994The microwave induced emission spectrum of gaseous HfS has been studied in the region 11 000-21 000 cm−1. Six band systems, not previously observed, have been photographically recorded in grating spectrographs and rotationally analysed. Five of the transitions terminate on a common lower state, the X1Σ state.

Intrinsic Self-Trapped Emission in 0D Lead-Free (C4H14N2)2In2Br10 Single Crystal.
Angewandte Chemie, 2019Low-dimensional lead halide perovskite materials recently have drawn much attention owing to the intriguing broadband emissions, however, the toxicity of lead will hinder their future development. Herein we report a novel lead-free (C 4 H 14 N 2 ) 2 In 2
