and the corresponding secular determinant.
Homework Answers
Since B and C both orbital basis are on one atom,so we can take either A and B for overlap or A and C ,to form Secular determinant equations.
When we consider heterogeneous molecules, the degeneracy is not present, and we must rethink the results.
