Solution LAB2 guanine

• Back to the previous page: Electronic properties of isolated molecules#Exercise1

• Once you have Avogadro installed, open it and let's use the molecular builder to visualise a Guanine molecule:

Build --> Insert-->Fragment-->nucleobases-->guanine

Click on the selection settings "arrow" and right click to visualise the molecule.

Clicking on manipulate settings "hand" you can then rotate the molecule.

• Now we perform a classical relaxation using an Avogadro built-in Force Filed

Extension-->Molecular Mechanics and we choose a FF

Extension-->Optimize geometry

In few steps we have our relaxed geometry.
