The oscillator strengths of two ultraviolet molecular lines expected to be seen in diffuse interstellar clouds have been measured. For the 1290.257 A° line of HC1, f=0.16±0.06. For the 1114.225 A° line of H2O, f=(5.0±2.0)x10−3. These results have been used in conjunction with observational data to compare measured and predicted column densities of these molecules in the ζ Óphiuchi cloud.
