Observations of infrared umbral and photospheric spectra in the region of the CO fundamental vibration-rotation bands have revealed the presence of lines due to the isotopic molecules 13C16O, 12C17O, and 12C18O. Preliminary analysis of a particularly clean spectral interval ( em 1) supports the result that the solar 13C/12C abundance ratio is terrestrial to within i 15 percent and indicates that the solar 180/iSO and 170/ISO abundance ratios are terrestrial to within 35 percent and a factor of 2.5, respectively.
