Mapping the molecular axes of pentacene-d₁₄ doped in p-terphenyl single crystal using pulsed EPR technique in near zero magnetic field

Abstract

The pulsed electron paramagnetic resonance (EPR) technique using computer controlled three-dimensional (3D) near-zero fields (NZF, 0–1.5 mT) have previously been reported. This paper reports on a comprehensive NZF pulsed EPR study of pentacene-d ₁₄ doped in p-terphenyl (PDPT) single crystals. Molecular symmetry axes are determined from the analyses of these NZF EPR spectra.
