โœฆ Synopsis

In order to determine the relative transition probabilities (t.p.) of the zinc atom, we measured the intensities of lines ~tnd bands in the spectrum of a d.c. carbon arc in air with one electrode containing a mixture of ZnO and MgCO 3 or MgO.

In table I the relative intensities of the components within several triplets are given. These intensity ratios are in good agreement with the multiplet intensity rules.

The mean values of the product of t.p. and statistical weight of the upper level for the measured singlet and triplet lines are shown in table . In order to obtain the approximate absolute values in sec -1 the values of table II have to be multiplied by ca. 4,6 . l0 s.

The relative transition probabilities (t.p.) of some triplet lines in the spectra of calcium and strontium have been determined with the aid of the relative intensities of these lines in the emission of the column of an electric arc, measured according to the photographic-photometric method. The tem
