We investigated the crystal growth, electron paramagnetic resonance (EPR) and optical absorption spectra of L-threonine doped with Cu2+. The quality, size and habit of the single crystals grown from aqueous solution by the slow solvent evaporation and by the cooling method vary when the impurities are introduced during the growth process. The angular variations of the EPR spectra of single crystal samples at room temperature and 9.77 GHz with the magnetic field orientation in three crystal planes (ab, bc and ac) show the presence of copper impurities in four symmetry related interstitial sites of the unit cell. These spectra display well resolved hyperfine couplings of the S = ½ of Cu2+ with the ICu=3/2 of the copper nuclei. Additional hype...
