Fig. 7.35 Homoclinic trajectories connecting the ð3; Æ1Þ saddle-nodes on the separatrix of the
torus about the Li atom in the LiH molecule. The arrows indicate the direction of the eigenvectors
of the transposed Jacobian matrix $J
B at the stagnation points. An asymptotic wavy line flows
across the stagnation loop, about its centre
Fig. 7.36 The current density field for LiH in a field perpendicular to the plane containing the
nuclei, with jB j ¼ 1 au. Diatropic (paratropic) current density is clockwise (anti-clockwise). The
maximum intensity of the J
B field is 0.58 au, truncated to 0.10 in the perspective view on the right.
Corresponding contours start at 5:0 Â 10
À3 au and are 5:0 Â 10
