Distinguished for his knowledge and work in general chemistry, and in particular for the application of physical methods to the elucidation of problems of structure of chemical substances, and to the discovery of new chemical processes and methods at the Government Laboratory. Thus he has discovered the structure of alkaloids from ultra-violet absorption spectra and is engaged on similar work on organic ethers and esters. He has investigated the infra-red spectra of ammonia, phosphine and arsinine (see Proc. Roy. Soc.) and of diamond (Phil. Trans., 1934, and Proc. Roy. Soc., 1936) and of hydroxy-bodies (Proc. Roy. Soc., 1937) the absorption of CH2 groups at 3 P (Proc. Roy. Soc., 1938), quinoline and isoquinoline at 3 P (J. Chem. Soc. 1939) and the dielectric constant and refractivity of gases at different pressures, relation between force constants, internucler distances and dissociation energy (J. Chem. Soc. 1938, 1939). He also represents the Government Laboratory and the Chemical Society on various bodies, official and scientific. |
