subject of this investigation, occur exclusively for chemically bivalent 
elements. For univalent and trivalent elements there occur no Greek 
complexes. 
After these more general remarks I will now set forth in what 
way I have carried out the inquiry as to the possible validity of the 
“Kombinationsprinzip ’. 
On a closer examination of the different types of the abnormal 
ZeRMAN-effect for the complexes mentioned it strikes us that for most of 
them the distances of the components from the original line are multiples 
of half the distance of two components from the normal Lorentz-triplet. 
When we call ¢ the change of energy which a path must undergo 
for an electron jumping from that path to an unchanged path to 
emit light corresponding with one of the components polarized L of 
the normal LoreNtz-triplet, while jumping from the unmodified path 
it emits light of a frequency of vibration equal to that of the middle 
component polarized //, then 
= — 
h 
will indicate the difference in frequency between the two before- 
mentioned components. 
Accordingly this e must be proportional to the 5. 
I have now introduced the hypothesis that through the magnetic 
field each of the initial- and final paths splits up into two or more 
paths, which present energy-differences with the original path of 
En. 5 m=. je nk 
Then I have examined what values of n must be assigned to 
each of the initial and final paths to enable us to explain the 
observed components. 
This yielded the following results:

Then we get the following types for the Zeeman-effect for the 
different complexes.
