An analysis of Cu iii based on observations from 500 to 6900 Å is presented. The low structures 3 d 9 and 3 d 8 4 s are complete, including the rarely, if ever before, found 3 d 8 ( 1 S)4 s 2 S. The 3 d 7 4 s 2 includes 4 F, 2 F, 2 G, and 2 H but the 4 P, 2 P, a 2 D, b 2 D have eluded all attempts to find them. The ionization potential calculated from 4 s , 5 s , 6 s 44 F 4 1 / 2is 296 980 cm -1 but by a comparison with Ni II which has a longer series an approximate value of 297 140 can be estimated. The 3 d 8 4 d group is complete, except for one level, as is 5 d based on 3 F and 1 G, the other 5 d groups being incomplete. 3 d 8 ( 3 F)4 f is complete and 26 levels based on 1 D, 3 P, 1 G are known. 3 d 8 ( 3 F)5 g is incomplete and a few levels based on 1 D and 1 G have been found. A discussion of the validity of the analysis of Cu iv by J. F. Schröder and Th. A. M. Van Kleef is given.
