Abstract
SOME simple relations appear to exist between the refractivities of a number of gaseous compounds and their constituents in the gaseous state which, so far as I know, have not hitherto been published. The refractivity of an atom depends largely on the outer electrons which are loosely bound to the nucleus. Previously it has been considered that when combination occurs between atoms the outer electrons are so distorted that the refractivity of a molecule is not related in any simple way to the refractivities of the constituent atoms and that the deviation from an additive law is a measure of the distortion (cf. Fajans and Joos, Zeit. f. Phys., vol. 23, p. 1; 1924; Born and Heisenberg, Ibid., vol. 23, p. 388; 1924; Havelock, Phil. Mag., vol. 3, pp. 158, 433; 1927).
