The dissociation energy of aluminium monoxide

Abstract

The absorption spectrum of AlO has been observed in the wavelength region 2000-3000 Å using a shock tube. Discrete band absorption and continuous absorption were observed. It is suggested that the continous absorption is a dissociation continuum of AlO and its long-wavelength edge gives a value of 4 54 ± 0.01 eV for the dissociation energy.
