Major scientific contributions

Ionel Solomon made major contributions to the fields of:Nuclear Magnetic Resonance (NMR)[1] doi:10.1103/PhysRev.99.559, Solid state physics, Semiconductors[2], and Photovoltaics[3]. In Nuclear Magnetic Resonance he derived fundamental equations that bear his name, and specify the nuclear spin-echo response and dipole-dipole interactions in solids (the Solomon equations)[4][5]. * Résonance magnétique (1955-1965) : Découverte de la relaxation dans un système de spins couplés.
