Electric Dipole Moments of Some Heterocyclic Cyclobutane Derivatives in Benzene Solution

چکیده
acetonitrile oxide IIa to la, it was considered remarkable that of the four possible isomers Ilia—Via three only were detected and isolated, i.e., the anti-trans Ilia, the anti-cis IVa and the syn-trans\ a. The assignment of these configurations was made on the ground of n.m.r., Raman and i.r. spectra, as well as X-ray structure analysis [2, 3]. Useful additional information may be obtained from the dipole moments of the different adducts, since their values ought to be strongly dependent

Microscopic Parameters in the Excited State of Toluene and Some of Its Haloderavatives
The Ultraviolet-visible (UV) spectra of toluene, ortho-bromo and para-bromo toluene in different solvents have been studied. The electric dipole moments and polarizabilities in the molecular excited electronic states were determined. It was found that the electric dipole moments for the excited states (µ*) and the ground states (µ) of these compounds are equal, and the change in dipole moment i...

متن کاملComparative study of electroabsorption spectra of polar and nonpolar organic molecules in solution and in a polymer film.
Electroabsorption (EA) spectra of polar and nonpolar molecules of coumarin 153 (C153) and pyrene in solution and in a polymer film of polymethylmethacrylate (PMMA) have been measured in the UV-visible region at room temperature. The shape of the EA spectra of C153 in benzene, 1,4-dioxane, or monochlorobenzene remarkably depends on the angle between the polarization direction of the absorption l...
