| Abstract: | Libethenite, a copper phosphate mineral originated from Congo is used in the present studies. Optical absorption spectrum is due to Cu(II), which is in rhombic distortion. Whereas EPR results show that Fe(III) and Mn(II) are also present in the mineral. MIR and Raman spectral features are attributed to phosphate fundamentals and lattices vibrations of CuO respectively.
