| Abstract: | Equivalent width calculations for some electronic and vibration-rotation transitions of the molecules PO, PH, MgH+f, and CN have been carried out for a few umbral, photospheric, and facular model atmospheres. It appears that a few weak lines of these molecules might show up in the umbral spectrum. Le Blanc bands of CN are too weak for detection in the solar spectrum. |
