Abstract
IN a recent letter to NATUHE, H. H. Van Iddekinge (NATURE, 125, 858; 1930) communicated the observation that in the emission spectrum of S2 the same bands occurred as in the absorption spectrum with the exception of those bands which are diffuse in the absorption spectrum (Henri and Teves, NATURE, 114, 894; 1924; and Rosen, Z. f. Phys., 52, 16; 1928). According to Van Iddekinge (see also Kronig, Z. f. Phys., 62, 300; 1930), this is readily explained by the fact that the diffuseness of the band lines is due to a spontaneous dissociation of the molecule in the upper state of these diffuse absorption bands (pre-dissociation) which occurs before radiation can take place; emission of these bands cannot therefore be observed.
