## Abstract

The relaxation modes and rates of a single polymer chain are studied by Monte Carlo simulations of the bond fluctuation model. On the basis of the method proposed by Takano and Miyashita [J. Phys. Soc. Jpn. 64 (1995) 3688], the approximate relaxation modes and rates are obtained by solving a generalized eigenvalue problem for the correlation matrices C_{i},_{j}(t) = <R_{i}(t) · R_{i}(t)>/3, where R_{i}(t) denotes the position of the ith segment relative to the center of mass of the polymer chain. For a chain of N segments with the excluded volume interaction, the contribution g̃_{i,p} of the pth slowest mode to R_{i} shows the i-dependence g̃_{i,p} α cos[(i - 1/2)pπ/N], which is the same as that of the Rouse model. The behavior of the relaxation rate λ_{p} of the pth slowest mode is in good agreement with the theoretical prediction λ_{p} ∼ (P/N)^{2v+1}, where v ≃ 0.588 is the exponent for the swelling of a polymer chain in good solvent.
