Abstract
Wave-lengths and frequency separations of the fine-structure components of 173 spectral lines in singly ionized praseodymium are given. It appears, as may be seen from a reproduction of some of the fine-structure, Fig. 1, that each group of six fine-structure lines has the same general appearance but varies in total intensity and width. In some lines given below the intensities and frequency separations within each group decrease toward the red, while all of the rest show similar degradation toward the violet.Keywords
