  • Title: Spectral investigations on melanterite mineral from France.
    Author: Reddy SN, Rao PS, Ravikumar RV, Reddy BJ, Reddy YP.
    Journal: Spectrochim Acta A Mol Biomol Spectrosc; 2001 May; 57(6):1283-7. PubMed ID: 11419470.
    Abstract:
    EPR, Optical and IR spectral studies on a naturally occurring mineral melanterite are carried out at room temperature. EPR studies indicate the presence of Cu(II) ion in tetragonally distorted octahedral site and hyperfine lines could not be resolved due to higher concentration of the paramagnetic impurity in the mineral. Optical absorption spectrum is a characteristic of Fe(II) and Cu(II) ions. Crystal field parameters are evaluated. IR spectrum confirms the presence of water and sulphate ions.
