years interest in such relatively new analytical techniques
I a s gas chromatography has tended t o overshadow developments in other important analytical areas. W e are happy, therefore, t o note t h a t developments in infrared and magnetic resonance were highlighted at, tlic recent ACS meeting in New York. T h e fact t h a t 600 or more attended the one-day I R symposium indicates t h a t much pioneering work is st,ill under way in many laboratories and t h a t this \vel1 known field is still a fertile one for significant advances. One subject of particular interest was the discussion of infrared spectra in aqueous solution. Except where tritium or deuterium is used, I R work in water solution is normally impossible. E. R. Blout, of the Children’s Cancer Research Foundation and Harvard Medical Scliool, described interesting applications to cliemical problems of biological interest using H 2 0 and D 2 0 solutions. Another interesting I R paper concerned surface study research done a t the General Electric Research Laboratory by R. S. McDonald and B. F. Riley. This work, which is concerned essentially with monomolecular layers, incrcases our knowledge of this important area. IYliile I R is generally thouglit of with respect to organic materials, it docs have sonit useful applications in the inorganic area. Some of t h e probleins, advantages, and limit,ations were noted by F . A . Miller of the ZIIellon Institute. J5”e noted much interest on the p a r t of the audience in the Symposiuin on Nagnetic Resonance Methods. M a n y of those present were anxious to learn more of the advances in instrumentation, methods, and tecliniques in this relatively new field. Like many other instruincntal techniques, thc skill of the operator is a vital factor in obtaining good rcsults. This was well s h o a n in a presentation by Bhrry Coniiiioner of TVashington University. IIc applied elcctron spin rcsonance to the study of bioclieiiiical and biological roles of free radicals. H e observed characteristic variations in free radical concentrations during certain physiological activities and a s a result of certain pathological proccsscs. T h e results indicate t h a t electron spin resonance analysis can be employed in some instances a s a diagnostic tool teclinique in connection with cancer pathology and certain liver diseases. It seems likely t h a t future research using elcctron spin resonance will help push b a c k , t h e boundaries in studies of living systems. M-e commend the offices of the Division of Analytical Chemistry in arranging such informative programs on timely topics.
