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...

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 ...

A new signal amplification system with an auto-inductive mode of action and distinct chemiluminescence output was developed. The system is composed of a unique structural motif that combines a chemiexcitation mechanism with a quinone-methide elimination into a signal building block. As demonstrated with a probe designed to detect fluoride, an auto-inductive chemiluminescence signal amplificatio...

Accurate assessment of reactive oxygen species (ROS) concentrations may help in the diagnosis of infertility. The chemiluminescence technique, which uses a luminometer to measure ROS, is a common method of assessment. A better understanding of the chemiluminescence technique will allow its proper application in reproductive medicine. A wide range of luminometers are available in the market, and...
