The Raman spectra of the mixed(naphthalocyaninato)[tetrakis(4-n-butylphenyl)porphyrinato] rare earth double-decker compounds M(Nc)(TBPP)(M = Y,La,Ce,Eu,Dy,Lu)were studied with density function theory for the first time.The results reveal the fingerprint band for naphthalocyanine around 1455–1615 cm-1 and porphyrin around 693-749 cm-1.
