Abstract
The splay orientational elastic constants for the nematic phases of a serie
s of dimeric alpha,omega-bis (4-cyanobiphenyl-4'-yloxy) alkanes have been d
etermined by the method of Freedericksz threshold transitions in a magnetic
field. A dramatic odd-even effect in the dependence of the elastic constan
t on the spacer length of the compounds investigated was revealed. It was s
hown that the splay elastic constant for the nematic dimers increases with
increasing length of the molecules.
