An ultraviolet photoelectron spectrum of phenyl alpha-nitronyl nitroxi
de (PNN) has been studied in the gas phase, in order to understand the
potentiality of the alpha-nitronyl nitroxide radical family yielding
ferromagnetic intermolecular coupling. The observed spectrum has been
well interpreted with the help of CNDO-CI calculation. Very strong spi
n polarization effect has been suggested, which is advantageous for th
e intermolecular ferromagnetic coupling.
