Jaffe Title: Conjugation of Several Phenyl Radicals Bonded to a Single Central Atom Journal/Source: J. Chem. Phys., 22, 1430-1433, (1954); http://dx.doi.org/10.1063/1.1740411 Data: diagram, table Energy/Wavelength range: 220 - 290 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: solution (95% ethanol) pH: Comments: Spectroscopic evidence is used to show that phenyl radicals are only weakly conjugated with central atoms (S, P, As, Sb, Si, Sn, Pb) not having unshared valence electrons.
