In two earlier papers dealing with the hyperfine structures in the spark spectrum of iodine (Part I (Tolansky 1935) and Part III (Tolansky and Forester 1938)), the partial analysis of a large number of lines has been reported. The basis of the analysis made in Part III was the multiplet classification given by Lacroute (1935), according to which the lines reported in Parts I and III belong largely to the (4 S) and (2 D) systems, intercombinations being rare. If this classification is correct, certain anomalies arise in the interpretation of the hyperfine structures, as already discussed in Part III.
