Abstract
WE have found that in a hot-wire Clusius column operating with water-vapour, molecules containing oxygen-18 concentrate at the top of the column. This is an unexpected result, since it implies that the water molecule under these conditions must be softer than a Maxwellian molecule. From our results an approximate calculation on the basis of the Furry and Jones theory1 indicates a force-factor of 4.9.
