 Dear CCL members,
 Can a virtual(unoccupied) orbital have negative eigen value.Generally occupied
 orbitals have negative eigen value and unoccupied orbitals have positive eigen
 values.If we get any negative eigen values for unoccupied orbitals was that
 mean optimization not done correctly.Can any one of you please clarify my
 doubt.
 Thank you so much
