摘要：

Multifrequency EPR spectra in the 94 to 550 GHz range were performed on solid air samples condensed at 5 K in the waveguide of a single pass probe, The 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 splitting 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.
