 Title    Three-membered Rings. Molecular Structure and Conformation of Aryl Substituted Oxiranes by Dipole Moment Measurements  
 Abstract    and C a r l o B a t t i s t i n i , B r u n o M a c c h i a , a n d F r a n c o M a c c h i a The electric dipole moments of some styrene and trans-and cis-stilbene oxides have been measured, in benzene. From these data some bond angles have been calculated and it has been deduced that in the styrene derivatives the phenyl group is in rapid interconversion about the bond with the triatomic ring.

 Title    Dielectric Measurements and Molecular Structure. Styrene Oxides and Phenylcyclopropanes  
 Abstract    The effects of electronic structure and conformation of the molecules YC6H4CHOCH2 1 1 (Y = o, m, and p-Cl) and Y'C6H4CHCCl2CH2 (Y' = o, and m-Cl) have been studied in benzene between 10.0 and 70.0 °C. In the oxirane systems the conjugation between the two rings is very small, if present at all; consequently, in the absence of steric and/or electrostatic hindrance internal rotation is observed. In the cyclopropane systems ex-amined these steric effects are sufficiently important to completely immobilise the molec-ular structure.
