Abstract:
The partial pressures of 20 ionic molecular species are reported here for standard facular, photospheric and sunspot model atmospheres with a view to picking up ionized molecules for a possible identification in the solar spectrum. Comparing the partial pressures with those of the molecule SiH⁺, which is already detected in the solar spectrum, it appears probable that additional ionic species can be identified in the same spectrum. To predict the line intensities of such species, accurate values of oscillator strengths and dissociation energies are needed.
