| Description |
294-300
The temperature of the disc integrated sunlight has been calculated by measuring the intensities of 113 rotational lines belonging to the R and P branches of the 0-0, 1-1 and 2-2 bands of the A<sup>2</sup>Δ<sub>5/2</sub>-X<sup>2</sup>Π<sub>3/2</sub> transition and 0-0 and 1-1 bands of A<sup>2</sup>Δ<sub>3/2</sub>-X<sup>2</sup>Π<sub>1/2</sub> transition of a CH molecule. The Fourier transform spectroscopic data has been taken from solar flux Atlas for the visible and near infra-red prepared by Wallace (NSO Technical Report #11-001 2011). The temperature comes out as 3300±121 K, less than the surface temperature of the photosphere of the sun as expected. |
