Aller, L. H. ; Keenan, P. C. Abstract Spectra of R Andromedae at its 1946 maximum and of j# Cephei have been measured in the photographic infrared region. Wave lengths, identifications, and estimated intensities are given for the atomic absorption lines as well as for a number of band heads of the infrared system of CN. The only strong emission features noted in R And at maximum are the lines of Ca II at X 8498, 8542, and 8662. The intensities of the atomic lines imply that R And is less luminous than j# Cep but is brighter than an ordinary M-type giant.
