  • Rezonanța Electronică de Spin ( RES )--care include și Rezonanța Electronică Paramagnetică (REP) -- este fenomenul fizic de absorbție rezonantă de microunde de la o sursă de microunde de către un sistem cu spini electronici „neîmperecheați" (adică, ce nu sunt cu spini anti-paraleli) dintr-o probă macroscopică în prezența unui câmp magnetic extern care ridică degenerarea nivelelor (energetice) electronice de spin.
