Fluorescence spectra of PN and BF

Kinetics of some gas-phase elementary reactions of boron monofluoride

“…2 1 The emission spectrum of the lamp was similar to that reported in Ref. 21. The only discernible spectral structure other than those attributable to the AIn + XIE transition in BF were the two boron atom resonance doublets at 208.9 and 249.7 nm.…”

Rovibronic spectroscopy of PN from first principles

“…15 shows a simulated non-LTE absorption A 1 Π–X 1 Σ + spectrum of PN to compare to the experiment of Moeller and Silvers. 13 Most of the major features are again shifted by ∼13.5 nm. We attribute the relative difference in strength of peaks between theory and experiment to difficulty in reproducing the non-LTE behaviour of the experiment, due to the lack of necessary information in the original paper.…”

“…Figure 16 Fig. 15 Comparison of an A 1 Π X 1 Σ + simulated emission spectrum (panel a) with that recorded by Moeller and Silvers 13 (panel b). The number at the top indicates the centre of the peak.…”

“…The visible A-X band system was first observed by Curry et al 33 and there have been several subsequent laboratory observations. 13,19,21,54 Below we compare our results to the experimental spectra; an overview spectrum for the A 1 Π-X 1 Σ + band system at Figure 12 Calculated absorption spectra of the A 1 Π-X 1 Σ + system at 2000 K with a Gaussian profile of HWHM=1 cm -1 .…”

“…Many other subsequent spectroscopic studies have taken place including photoelectron, 12 fluorescence, 13 matrix infrared, 14 microwave [15][16][17] and Fourier Transform Infra-Red (FTIR). 18 Most of the high resolution spectroscopy experiments with PN concentrated on the electronic system A 1 Π -X 1 Σ + , 11,13,[19][20][21] with E 1 Σ + -X 1 Σ + being confirmed afterwards, [22][23][24] and several valence and Rydberg states have been studied as well. 25,26 Measured lifetimes can be important indicators of intensities and Einstein A coefficients.…”
