Abstract:A general treatment of linear polymers is developed using MNDO and the tight binding approximation. Analytical expressions are derived for first derivatives of the energy. These are used to calculate geometries vibration frequencies and elastic moduli. Application of this treatment to polyethylene gave results in good agreement with experiment and also a reasonable account of its electronic band structure.
