The instrumental setup and preliminary results of the experiments performed during the eclipse are briefly reported.

The partial pressures of 20 ionic molecular species are reported 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. ...

The recently published values of oscillator strengths for the Phillips bands were checked with those obtainable from the solar spectrum. The results of (1982) Erman et al. based on the assumption of a varying electronic ...

The MACKKL photospheric model and the latest oscillator strengths are used to obtain a solar abundance of iron close to the meteoritic value N(Fe) = 7.51 +/- 0.01. This helps to eliminate the discrepancy between photospheric ...

Several unidentified spectral features in the solar spectrum are listed by Moore et al. (1966). They are traceable in the atlas by Delbouille et al. (1973). We attempt to identify some of these features in the region lamda ...

Utilizing Lieze solar atlas and solar photospheric models, we derived log gf values for the spectral lines in the wavelength range λλ 6209 - 6273 Å. These values, intended for use in a future study of high resolution reticon ...

Four photospheric models have been utilized to derive model based rotational temperatures of the (0-0) band of the Swan system of C/sub2/ and that of the green system of the MgH molecules. The dissociation energies were ...

We summerise here some of the recent advances in deriving molecular and atomic parameters using the high resolution spectra of the sun
