ABSTRACT (_By Cable, through Science Service, Washington, D.C._) PROF. RAMAN'S brilliant and surprising discovery that transparent substances illuminated by very intense monochromatic
light scatter radiations of modified wave-length, and that frequency difference between emitted radiation and one exciting medium is identical with frequency of infra-red absorption bands,
opens up wholly new field in study of molecular structure. I have verified his discovery in every particular, using improved apparatus which makes it possible to photograph strongest lines
in few minutes. Anti-Stokes' terms of intensity nearly equal that of lines of wave-length greater than exciting line obtained chloroform, carbon tetrachloride, latter giving triplet
each side 4046, 4358, 5461 lines mercury arc. Raman reported no trace modified lines excited latter line, but are strong with carbon tetrachloride. Triplets short wave-length sides exciting
lines appear mirror images those long wave-length side, considering exciting line mirror. Crystalline quartz gives strong line identified as 20μ absorption band, and fainter line very close
exciting line corresponds infra-red absorption about 75μ. Raman's discovery thus makes possible investigation remote infra-red regions hitherto little explored owing experimental
difficulties. As yet I have found no line corresponding more generally known band quartz (eight and half μ). This expected as small energy exchanges between impinging light quanta and
molecules more probable than large; these correspond absorption bands very long wave-length. SIMILAR CONTENT BEING VIEWED BY OTHERS ALL ELECTROMAGNETIC SCATTERING BODIES ARE MATRIX-VALUED
