Theoretical analysis of dynamic effects of low-symmetric distributions of spins on EPR spectra in one-dimensional magnetic systems by the Mori's memory function method

Abstract

The problem of how EPR spectra in 1-d systems depend on the relation among directions of chain-axis, vibrational field and static field is discussed theoretically considering low-symmetric distributions of spins. Characteristics behaviors of shifts of resonance points obtained by numerical calculation agree well with observations in TMMC.
