In a previous $work1$ Dean's negative eigenvalue theorem has been used to compute the distribution of eigenvalues of a chain molecule containing randomly distributed mass defects. The method has been extended to conformational $defects2$ and, in the present work, to force constant defects. For a better understanding of the molecular dynamics of the chain, we have also applied the Givens-House-holder's method which allows to obtain the distribution of eigenvectors corresponding to approximate eigenvalues of very large matrices.
