Electron spin-echo modulation effects in disordered systems: Structure of traps for H and D atoms in frozen water solutions based on 1H and 2D nuclear modulation data

Abstract
Modulation effects induced by matrix protons and deuterons in the primary ESE from H and D atoms trapped in frozen water solutions of sulfuric acid have been analyzed. It has been shown that the nuclear quadrupole interaction in a deuterated sample additionally damps the modulation.
