Abstract:
The equivalent widths of P(51) and R(43) lines of the 1-0 and P(45) and R(56) lines of the 2-1 vibration rotation bands of SiO near 8 µm region, have computed for Zwaan's(1974) sunspots model at the centre of the disc. The predicted equivalent widths suggest a possible presence of these SiO bands in the sunspots spectrum.
