Abstract:
Equivalent widths for the lines of ionized molecules A1H⁺, CH⁺, CN⁺, CO⁺, MgH⁺, N2⁺, NH⁺, OH⁺ and SiH⁺ have been calculated in five facular and two photospheric models. The calculations suggest that CH⁺ should show up in facular spectrum. MgH⁺, OH⁺ and SiH⁺ may also be present while A1H⁺, CN⁺, CO⁺, N2⁺ and NH⁺ should be absent.
