It has been shaown that bound-bound opacity due to electronic transitions of molecules CN, CaH, MgH and TiO explains, in first approximation, the line haze opacity postulated by Zwaan (1974) for the region 0.5 µm to 0.9 ...

The equivalent widths of R1(26.5)lines,belonging to the 1-0,2-1 and 3-2 vibration bands of NO near 5.3 µm,have been computed for two different sunspot models at four positions on the disc.The computed equivalent widths in ...
