Equivalent widths for the lines of ionized molecules AlH+, CH+, CN+ CO+, 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 AlH+, CN+, CO+, N2+ should be absent.
