Abstract

Wave-lengths of N, C and O lines in the spectral range λ2317 to λ1080 have been determined with an accuracy of 0.01A to serve as wave-length standards in this region. A ten-foot focus normal incidence vacuum spectrograph having a dispersion of 5.5A/mm was used to compare second order N and C lines with first order Cu and Fe interferometer-measured standards. The results are compared with values given by Boyce and Rieke. The mean deviation from their values is 0.009A, the mean systematic deviation 0.001A. The use of the method of coincidences in determining tertiary standards is discussed.
