Observations have been made with the Effelsberg 100-m telescope of the 4.389-GHz absorption line of H2(C-12)(O-18) toward Sgr A, Sgr B2, W33, and W51. Comparison with earlier H2(C-13)(O-16) data shows that the H2(C-13)(O-16)/H2(C-12)(O-18) ratio is 5 + or - 1; that is, close to the terrestrial (C-13)(O-16)/(C-12)(O-18) value of 5.5, in all sources. The results are in agreement with those of Tucker et al. (1979) for formaldehyde, but differ significantly from the ratios obtained from carbon monoxide.
