The absence of Phillips bands in the solar photospheric spectrum and the presence of Swan bands seems to point to a non-LTE path for the formation and disappearance of C₂ molecules in the solar photosphere.

Equivalent width calculations for a line 1.83 μ of the 0-0 vibrational band of the Ballik-Ramesy band system has been carried out in two photospheric models- BCA and HSRA. Centre to limb variation of the above line is given ...

Withbroe'(1968) photospheric data on the equivalent widths of C2 lines for various positions on the solar disc have been utilized by us to determine the centre to limb behaviour of the rotational temperature.in view of ...

Predicted equivalent widths and profiles of facular CN lines are used here as a diagnostic tool for different model atmospheres.

The calculated rates of photodissoication, radiative association and the diffusion of CH and CO molecules show that the diffusion rates are many orders of magnitude smaller than the photodissociation and radiative association ...

Utilizing the model atmospheres proposed by Sobotka for umbrae of different sizes and those proposed by Maltby et al. for well-developed umbrae, at diffrent phased of solar activity, we examine themolecules C₂, MgH and TiO ...

Identification of the A¹ II -X¹ Ʃ transitions of the CH+ molecules in the solar spectrum was reinvestigated by using new laboratory data on molecules, standard photospheric models, the KPNO and the Liege solar atlases. We ...

The lower X¹Σg state of the Phillips and of the Mulliken band system of C₂ molecule lies very close to the X¹ ³πᵤ' the lower electronic state of the Swan system observed in the photospheric spectrum.

The partial pressures of 20 ionic molecular species are reported here for standard facular, photospheric and sunspot model atmospheres with a view to picking up ionized molecules for a possible identification in the solar ...

In a recent publication of the Bulletin of the Astronomical Society of India, the possibility of detection of the (1-0) vibration-rotation lines of HeH⁺ molecules in the solar photospheric spectrum has been suggested. ...
