split up into different paths, each with a somewhat different energy 
value, so that when jumping from and to these transformed paths 
the electrons would emit a vibration with a somewhat changed 
frequency ? 
If this question should be answered in the affirmative, it would 
follow from this that given the modes of splitting up of each of 
the paths (U, = etc), the observed types of ZreMar-effect might be 
found from this by simple subtraction, in other words, that the 
anomalous ZreEMAN-effect would follow the so-called ‘“Kombinations- 
prinzip’’. 
To answer the questions put I have done exactly the reverse. I 
have namely tried to determine whether in the material of obser- 
vation of the anomalous Zreman-effect indications were to be found 
of the validity or non-validity of the “Kombinationsprinzip”’. 
In what follows I will communicate some of the results obtained 
by me. 
As material has served what I had collected in (l.c.). In order 
to be able to treat a number of complexes as large as possible with 
a number of sequences as small as possible I have confined myself 
for my first investigation to the triple complexes, and added to this 
some single complexes with strange asymptote. 
These are collected in the following table:

For the types of Zeeman-effect that these complexes present, see (I.c.). 
From this material some general conclusions may first of all be made. 
When the electron jumps from an initial path to a ZF-path, the 
ZEEMAN-effect is more complicated than when from the same initial 
path it jumps to a 77'-path, and this in its turns is again more com- 
plicated than when from the same initial path it jumps to a J7"-path. 
It is therefore natural to assume that in a magnetic field the
