    "abstract": "A flexible scheme for decomposing the vibrational density of states in terms\nof pair vibrational density of states is presented. This scheme provides the\nlinkage between the site vibrational density of states and pair vibrational\ndensity of states so that vibrational modes, in particular localized modes, can\nbe conveniently examined in terms of the correlation between the vibration at a\ngiven site and those at its neighboring sites. Furthermore, within the\nframework of a total energy vibrational spectrum study, this scheme allows the\nanalysis of vibrational modes in terms of their electronic origin. A case study\nof the vibrational dynamics of the relaxed Si$_{87}$ cluster is carried out to\ndemonstrate the flexibility of the scheme in analyzing the properties of\nvibrational modes, particularly for complex systems with reduced or no\nsymmetry.",
