β¦ Synopsis
The relative transition probabilities (t.p.)~in the spectrum of Mg were determined by measuring photographically the intensities of the Mg lines, emitted by a B o 1 t z m a n n radiator, in our case, the positive column of a carbon arc in air with Mg-filled electrode(s). The temperature of the emitting gas was measured spectroscopically.
The relative t.p. of a few triplets were determined at different temperatures, both in a d.c. arc and in an a.c. arc. The good agreement, found in all cases, confirms the underlying assumption concerning the thermic mechanism of excitation.
The mean values of the product of t.p. and statistical weight for these triplets and for all other measured liries are shown in table IV and fig. .
The intensity ratios of the components of those triplets that have been measured completely, agree with those predicted by the sum rule.
