Abstract The analysis of high resolution emission spectra of isotopic enriched 130Te2 gave the rotational constants suggesting the transition as a σ - σ type. Heat of dissociation of Te2 is evaluated from the computed dissociation limit in the excited state.

The spectrum of ZnIn shows bands which can be analyzed into four systems. Two narrow systems at $\ensuremath{\lambda}4102$ and $\ensuremath{\lambda}4511$ appeared continuous. Systems at $\ensuremath{\lambda}5308$ ($B\ensuremath{-}A$) and $\ensuremath{\lambda}5625$ ($D\ensuremath{-}C$) were photographed with a dispersion of 5 \AA{}/mm.

The emission spectrum of SiN has been reinvestigated under high resolution in the spectral region 3100–5600 Å. Besides the well known B2Σ+–X2Σ+, three new transitions have been analyzed, two 2Π–2Π and one 2Σ–2Π. These three transitions have a lower 2Π state in common which appears to be the lowest excited A2Π state.

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 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+.

Quantitative modeling of the third harmonic emission spectrum of plasmonic nanoantennas.
Nano letters (Print), 2012Plasmonic dimer nanoantennas are characterized by a strong enhancement of the optical field, leading to large nonlinear effects. The third harmonic emission spectrum thus depends strongly on the antenna shape and size as well as on its gap size.

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 mechanism of using the anisotropic Purcell factor to control the spontaneous emission linewidths in a four-level atom is theoretically demonstrated; if the polarization angle bisector of the two dipole moments lies along the axis of large/small ...

On the emission spectrum of triphenylene
Journal of Luminescence, 1988Abstract The fluorescence spectrum of triphenylene in solution is compared to that of the melt and to that of triphenylene in the crystalline state. The latter is studied as a function of temperature. The changes in the relative intensities of the vibrational peaks with temperature are discussed.
