'[Dewar] joined George Downing Liveing, professor of chemistry at Cambridge, in an attempt to correlate line and band spectra with atomic and molecular states. They published seventy-eight papers between 1877 and 1904. Dewar's interest in spectroscopy stemmed from a fascination with Henri Sainte-Claire Deville's work on dissociation and reversible interactions and Norman Lockyer's controversial speculations on the dissociation of the elements at high temperatures. He contrasted Deville's exact experimental methods with Lockyer's conjectures, which he felt were based on insufficient evidence. Dewar and Liveing accurately determined the absorption spectra of many elements (especially metallic vapors) and compounds. They studied the general conditions affecting the excitation of spectra and, in particular, the ultraviolet emission spectra of many metals. They noted the contrast between single spectral lines, multiplets, and bands, and they attempted to identify the emitting agents for single, multiplet, and band spectra. They classified great, intermediate, and weak intensities with the spectroscopic series as principal, diffuse, and sharp, respectively. Their studies included the differences between the arc, spark, and flame spectra of metals; the emission spectra of gaseous explosions and of the rare gases; and the effect of temperature and concentration on the absorption spectra of rare-earth salts in solution' (D.S.B. IV: 79).…
