An emission spectral analysis was carried out on chemiluminescence emitted from UVB-irradiated squalene. The main emission species produced by the transition of (1 delta g) (1 delta g) and (1 delta g) (1 sigma g +) to (3 sigma g -) (3 sigma g -) were found by spectroscopic analysis of the chemiluminescence. When beta-carotene was added to the irradiated squalene, its spectral pattern changed dr...

Luminol (5-amino-2,3,-dihydrophthalazine-1,4-dione) is synthesized and its chemiluminescent properties are explored. Both spectral and physical data indicate that the luminol is sufficiently pure, despite a low yield. Chemiluminescence of luminol is observed in the presence of H2O2 and an oxidant enhancer. The quantum yield of the luminol chemiluminescence is determined to be moderate (0.10 ± 0...

Chemiluminescent reactions of calcium atoms in the metastablePJ and D2 states with CH3I and CD3I were studied in a beam-gas arrangement. Calcium monoiodide spectra associated with transitions from the electronic A Π, B Σ and C Π states to the X Σ ground state were recorded. Total collision and chemiluminescence cross sections were measured. It was found that isotopic substitution in the methyl ...
