Abstract
MEASUREMENTS of the hot spark spectrum of sulphur in the Schumann region have enabled me to classify partially the singlet system of S III and to locate the new terms with respect to the known triplet system by means of numerous intercombinations. It has been possible to find two singlet terms in K VI from Ekefors'1 data and to locate them with respect to the known triplets by intercombinations. The new terms are listed in Table 1.
