Abstract

The O¹⁸-benzophenone content of 100 to 700-μg. samples of 1 to 61 atom % enriched benzophenone can be determined with the mean accuracy of ±0.5% (absolute) from the infrared absorption intensity of their CCl₄ solutions at 1667 and 1637 cm.⁻¹, the locations of the C═O¹⁶ and C═O¹⁸ stretching bands. No weighing of the sample is generally necessary since the O¹⁸ content is calculated on the basis of the respective absorbances. It seems that this method can be used for the O¹⁸ determination in submicro samples of water after reacting it with pure dichlorodiphenylmethane.
