无机化学(5.3)Symmetry and Point Groups (Part 3)
In this chapter on "Symmetry and point groups," elements of molecular symmetry and point group are introduced. A transformation matrix for each symmetry operation is added to provide a computational know-how. An introduction to the group representation of symmetry operations, irreducible representations...
