Goldberg, Leo ; Mohler, Orren C. ; McMath, Robert R. Abstract Accurate wave lengths and measurements of percentage central absorption are given for nearly three hundred new solar lines discovered in the region 1.52-1.75 ~ of the infrared solar spectrum. The lines were found on high-resolution, direct-intensity tracings of the spectrum obtained at the McMath- Hulbert Observatory with the McGregor spectrometer and a Cashman cell. Ninety-three of the lines have been identified as belonging to neutral atoms of C, Mg, Al, Si, Fe, Mn, and Ni, mainly on the basis of wave lengths computed from term values. In addition, the third, seventh, and eighth members of the Brackett series of hydrogen have been identified, together with the Na I 4s-4p doublet at XX 22,054 and 22,081.
