Abstract
IN the course of the recovery of some heavy water residues by electrolysis, the gas (D2) was passed after purification through one side of the double tube (75 cm. in length) of a Rayleigh gas interferometer, while hydrogen gas produced by electrolysis of ordinary water and similarly treated was passed through the other side. A final steady shift of 24 drum divisions of the compensating plate was required to compensate for the difference of refractive index of the two gases. This is equivalent to 1·68 fringes of the mercury line = 5461, and hence the difference of refractive index of ordinary and heavy hydrogen in the visible region is (123 ± 2) × 108 at 760 mm., ordinary hydrogen being the greater. The gas passed when the final reading was observed was burnt and collected separately, and proved to be within 0·1 of 100 per cent heavy hydrogen (D2).
