Numerical studies have been done on some one-dimensional anharmonic lattices with nearest neighbor interaction. The spectral entropy 0 and the largest Lyapunov exponent X1 were calculated. The diatomic Toda lattice, the Lennard-Jones lattice, and the lattice interacting with 1/r repulsive potential
