A technique utilizing guanidine hydrochloride has been used to determine /sup 18/O//sup 16/O ratios in water. These O-isotope ratios have been considered in conjuction with /sup 18/O//sup 16/O ratios obtained from equilibration of CO/sub 2/ with surplus water to obtain a value for the carbon dioxide-water fractionation factor at 25/sup 0/C of 1.04143 +/- 0.00032 (99% confidence interval). This determination of ..cap alpha..CO/sub 2/-H/sub 2/O falls within the range of values cited in teh literature. 27 references, 3 tables.
