| Abstract: | An L-band (1–2 GHz) EPR spectrometer with static and oscillating magnetic fields parallel is used to obtain quadrupole coupling information through direct measurement of secondary (Δms = ±1, Δm1, = ∓1) transitions. Spectra and interpretations are presented for a test case, 63Cu/Pd(acac)2 powder, for which QD = 9±1 MHz and QE = 0.6 MHz are obtained. |
