Wave functions for the 3 d 4 s 4 p , 3 d 2 4 p and 4 s 2 4 p configurations of ScI are calculated, taking into account departures from SL ‐coupling and configuration interaction and on fitting the radial integrals to the experimental fine structure energies. Using these wave functions g J ‐values are derived. The intermediate coupled hfs matrix elements of the 3 d 4 s 4 p configuration are reduced to the unknown electron coupling constants a s , a p and a d and calculated on estimating these constants from the spin‐orbit coupling constants and fitting them to some experimental A ‐values. By this way the absolute phases of the experimental A (( 1 P ) 2 D )‐ and A (( 1 P ) 2 F )‐values are obtained. Good agreement between calculated and most experimental data has been achieved.
