The correlation function of the size-bond parameter-Raman shift was formulated based on the bond order-length-strength( BOLS) correlation and core-shell model. The quantitative information of the bond length,bond energy and the effective atomic coordination number( CN) of the Ⅳmaterials was obtained. It is clarified that the size-induced phonon softening arises intrinsically from the undercoordinated atoms. Developed approach empowers the Raman technique in deriving quantitative.
