Abstract
Weak lines have been found close to positions indicated by theory for the 2s 1S0-2p 1P1 transition of N VI at 2896.4 AA and for O VII at 2450.0 AA; the 2s 3S1-2p 3P2,1,0 lines were identified at substantially the same wavelengths as published by others. The experimental results and theoretical work are applied to an evaluation of the ground term of C V and absolute terms of N VI and O VII.
