Abstract
Making use of a spectrometer with a salt prism and echelette gratings, and a Moll thermal relay, the authors have reexamined with increased resolution the four absorption bands of water vapor whose centers lie near 1.87μ, 2.66μ, 3.15μ and 6.26μ. The new study has greatly increased the number of measured lines. Near 6.26μ and 3.17μ the number has been more than doubled. The new lines are mostly weak ones, but the work has resulted in a better determination of the wave-lengths of many strong lines, which now appear as sharp single effects freed from the former confusion in which several lines were taken for one. The center of the harmonic of the band at 6.26μ is seen to be better placed at 3.168μ than it was formerly at 3.11μ. It also appears that this band has no absorption at the center, and is of the same type as the fundamental.
