The spectrum of arsenic was photographed in the 400–1500-Å region on a 3-m normal-incidence spectrograph using a triggered spark source. On the basis of the new measurements, the earlier analysis of As vii was confirmed, revised, and extended. All levels of the 3d9, 3d84s, 3d84p, and 3p53d10 configurations have been established. Least-squares-fit energy parameter calculations support the analysis. Eighty-five additional lines have been classified in the As VII spectrum.

I, intensity of the line on a scale 1–100.
Char., character of the line, given by the following codes: 1, normally sharp and symmetric line; 2, weak or hazy line (therefore difficult to measure); 4, wide line; 7, line on the shoulder of another line (therefore intensity as well as λ measurements may be less accurate); 8, asymmetric line shaded to the lower-wavelength side; 9, asymmetric line shaded to the higher-wavelength side; D, doubly classified line in which both components have about the same calculated intensity; T, triply classified line in which all three components have about the same calculated intensity; M, doubly classified line (the masked component has low calculated intensity compared with the other component); B, blended by a line of lower ionization or by an impurity line.
