The combustion process of stoichiometric aluminium/copper(II)oxide thermite was experimentally investigated in an optical bomb under inert atmosphere (N2) and ambient pressure. The reaction zone was monitored with UV/VIS emission spectroscopy and a colour high‐speed camera. The emission spectra were analysed by modelling of the background radiation and the characteristic emission of all molecular emitters in the reaction of Al/CuO. Based on this, the particles′ surface and gas phase temperature, the emissivity and the radiation of energy was determined by a non‐linear least squares fit between experimental and modelled spectra. This work presents the first modelling of the diatomic band system of Cu2 and CuO. The results obtained can help to understand the underlying processes in thermite combustion and the influence of radiation processes in modelling the combustion of thermite mixtures.

A high resolution spectrum of a sunspot umbra is used for identification of rotational lines due to (0, 0) band of the A 2 -X 2 + system and (0, 0), (1, 1), and (2, 2) bands of the B 2 + -X 2 + system of the molecule SrF. The published sunspot umbral spectrum obtained with Fourier Transform Spectrometer and solar telescope of National Solar Observatory/National Optical Astronomy Observatory at Kitt Peak was used for the study. The new identification of more than 200 SrF lines in the umbral spectrum confirms that this molecule accounts for the majority of lines in the spectral range 15050 to 15360 cm −1 and 17240 to 17300 cm −1 . Equivalent widths have been measured for well-resolved lines of these bands and the effective rotational temperatures have been estimated for which the presence is confirmed.
