... length ro can be identified with the average bond length of polyacetylene . Note that since dt / dr is less than zero ( the hopping is a decreasing function of separation ) and since po is positive , dV / dr must be less than zero when ...

... bond lengths r1 + 1 ( about the point r11 + 1 = ro ) shows that the configuration of equal bond lengths represents a saddle point , rather than a true minimum . Thus the equal bond length state does not correspond to the state of lowest ...
