Abstract
The equivalent widths of R 1(26.5) lines, belonging to the 1-0, 2-1 and 3-2 vibration-rotation 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 both models suggest a possible presence of these NO bands in the sunspot spectrum.
