Water molecules form clumps. New evidence that liquid water molecules form in clumps of two or more has been presented by Prof. Joseph W. Ellis of the University of California a t Los Angeles. The new evidence comes from the way in which infra-red or heat rays are absorbed by water. Certain new bands or dark patches observed in the infra-red spectrum favor the theory that the simple chemical units of two hydrogen and one oxygen molecules are probably linked in groups or even farm a lattice-like structure. This theory has not been in favor with chemists recently. However, some phenomena observed during the formation of ice lend considerable weight to the idea.Science Service
