Molecular polarisability. The conformation of N-phenylaziridine
Dipole moments and molar Kerr constants are reported for azidirine as a solute in cyclohexane and in benzene and for N-methylaziridine and N-phenylaziridine as solutes in cyclohexane. A dipole moment determination for N-p-fluorophenylaziridine in cyclohexane is also given. The data are analysed to determine the preferred solution-state conformation of N-phenylaziridine. Solvent effects on the proton magnetic resonance spectra of aziridine are discussed.
