摘要: In this part will be given a general description of the absorption bands found in these three gases, together with curves showing their occurrence region up to 17 μ, and evaluations maxima bands. Part IV relationships each other one gas, corresponding where occur, dicussed. A apparatus is I, its calibration procedure II, Which also give methods obtaining gases pure. It only necessary, therefore, say here that order get best definition which prism instrument capable, galvanometer was maintained at highest sensitiveness, spectrometer slits were scale, longer tubes selected for examination faint shorter strong bands, exploration conducted pressures varying from 1 1/16 or 1/32 atmosphere.
