Compare A., 1912, ii, 1114).-By application of the theory of quanta, it is shown that the frequency of molecular rotation can be obtained from t,he formula v = n . h/2+J, in which J is the moment of inertia, n an integer, and h is the fundamental quantum of energy. The rotation frequencies calculated from this
