The molecular vibration spectroscopy of the first pure organic ferromagneti
c compound, P-phase of para-nitrophenyl nitronyl nitroxide (beta p-NPNN)I h
as been studied by Raman spectroscopy. A primary assignment for the Raman s
pectrum of beta p-NPNN is made and this will serve as a base for future stu
dies of ferromagnetism of this material when the environment conditions (te
mperature, pressure, and so on) are changed. (C) 2000 Elsevier Science B.V.
