Conclusions
-
1.
A refractometric method was developed for the determination of the conformations of conjugated systems of the diphenyl type.
-
2.
The possibility of the use of correlation equations for the calculation of the exaltation and refraction of coplanar diphenyls in the liquid state was demonstrated.
-
3.
The angle of rotation between the benzene rings in certain alkyl- and halodiphenyls was estimated quantitatively.
