Abstract
Multifrequency EPR spectra in the 94 to 550 GHz range were performed on sol id air samples condensed at 5 K in the waveguide of a single pass probe, Th e spectra of molecular oxygen were observed and interpreted in the frame of the spin Hamiltonian model as axial S = 1 spectra with a zero field splitt ing parameter D = 3.572(3) cm(-1). The result of this study is relevant in the field of high field-high frequency EPR application in which solid air O -2 is a common paramagnetic impurity. (C) 2000 Academic Press.
