## The H_{100} cluster II

In this section you will calculate the wavefunction
and the energy level diagrams for the
linear and cyclic H_{100} clusters,
where the distance H-H has been doubled with respect
to the previous section, H_{100} .
Both the H_{100} clusters are hypothetical,
and the distance has been modified in order to study
the effects on the electronic structure.

**Exercise 1**: Start DLVisualize,
run a CRYSTAL calculation for the linear case:
H100_linearII.inp

**Exercise 2**: Run a CRYSTAL properties calculation
of the energy level diagram + the density of states

for the H_{100} linear cluster,
as explained in **Exercise 4**
for H_{4}.

**Exercise 3**: Start DLVisualize,
run a CRYSTAL calculation for the cyclic case:
H100_cyclicII.inp

**Exercise 4**: Run a CRYSTAL properties calculation
of the energy level diagram + the density of states

for the H_{100} cyclic cluster,
as explained in **Exercise 4**
for H_{4}.

**Questions:**
- What are the differences between the current plots of the energy levels
and the ones obtained in the previous section,
H
_{100}?
- Is there a change in the shape of the density of state,
when comparing the current plots of the DOS,
with the ones obtained in the previous section,
H
_{100}?
