Description
Absorption due to the 3-1 vibration-rotation band head of 28Si16O at 2473 cm-1 has been detected in the atmospheres of a number of evolved giant and supergiant stars. The column density of 28Si16O in a Ori is determined to be 1021.7 cm- 2 None of the stars observed indicate measurable absorption due to the band head of 30Si16O at 2467 cm-1. A lower limit of 20 is established for the ratio 28Si/3OSi in a Sco. Subject headings: abundances, stellar - molecules - spectra, infrared
