Abstract
Low noise photoelectric scans of the solar disc and sunspot spectra are examined for lines attributable to the (0, 0) band of the SiH system |${A}^{2}\,\Delta-{X}^{2}\,\Pi$|. Satisfactory identifications are established. A model atmosphere calculation provides a result for the band oscillator strength: f00 = 0.0045. Isotope shifts are calculated for the less abundant species, Si29H and Si30H. It is shown that the isotopic abundances are probably normal.Keywords
