## The H10 cluster

In this section you will calculate the wavefunction and the energy level diagrams for the linear and cyclic H10 clusters.

Exercise 1: Start DLVisualize, run a CRYSTAL calculation for the linear case: H10_linear.inp

Exercise 2: Run a CRYSTAL properties calculation of the energy level diagram + the density of states
for the H10 linear cluster, as explained in Exercise 4 for H4.

Exercise 3: Start DLVisualize, run a CRYSTAL calculation for the cyclic case: H10_cyclic.inp

Exercise 4: Run a CRYSTAL properties calculation of the energy level diagram + the density of states
for the H10 cyclic cluster, as explained in Exercise 4 for H4.

Exercise 5: Plot the eigenvalues as a function of the number of atoms in the cluster
(start from the hydrogen atom to the 10-atoms cluster),
for both the linear and the cyclic ones.

Questions:

1. What are the differences between the two plots?
