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.

The emission spectrum of berkelium
Atomic Data and Nuclear Data Tables, 1978Abstract The berkelium emission spectrum was observed from 2540 to 9800 A with an electrodeless lamp as a source. The wavenumber, wavelength, and relative intensities of the 1930 strongest 249Bk lines are reported. In addition, information on hyperfine structure, Zeeman effect, spectrum assignment as neutral or singly-ionized lines, and energy level ...

Abstract A spectrum, found in the 360- to 420-nm region following hollow-cathode excitation of InCl 3 /In/He mixtures has been attributed to the InCl + ion. Sixteen bands have been classified for the system which has been identified through rotational analysis to be B 2 Σ- X 2 Σ, consistent with photoelectron observations by Berkowitz and Dehmer.

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 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 HgAr+
Journal of the Chemical Society D: Chemical Communications, 1970Emission from the ion HgAr+ has been observed in low-pressure discharges: the high-resolution spectrum yields a full assignment of the transition and the length, vibrational frequency, and dissociation energy of the bond.

Abstract A new system of emission bands has been observed in the visible region of the spectrum. The bands exhibit the characteristic rotational structure of a 3 Π i - 3 Π i electronic transition. Rotational analysis and isotopic studies of these bands indicate that the carrier of the spectrum is the species AlN. The rotational analyses of the (0-0)
