Abstract

This theoretical work reports full quantum-mechanical analysis of the potassium far-wing photoabsorption spectra. The accuracy of the adopted K2 potential-energy curves and transition dipole moments is established by computing the vibration-rotation levels and the radiative lifetimes of the excited molecular states and by determining the variation law with temperature of the diffusion coefficient of atomic K(4p) in a ground potassium gas. The pressure-broadening calculations revealed that the photoabsorption spectra have, in the temperature range 850-3000 K, a satellite structure characterized by the presence of three peaks around 718.7 nm in the blue wings and 1048.1 and 1100.8 nm in the red wings. This theoretical work could in particular point out the occurrence in the blue wing of a satellite originating from the bound-free B←X transitions near 731.5 nm. All these results agree quite well with the experimentally measured values.
