QM - complement for Griffiths

[Avatrin]

Hi
I am currently trying to learn quantum physics using David J. Griffiths textbook. However, in chapter 4 and 5 he lost me a little. I would prefer a textbooks that handholds me through solving the PDE's rather than just giving me the solutions.
The topic of these chapters are:
QM in three dimensions (Schrodinger equation in spherical coordinates, the hydrogen atom, angular momentum, spin)
Identical particles (two particle system, atoms, solids, quantum statistical mechanics )

any tips? Maybe a mathematics or physics textbook to complement this?

You won't need anything else. If you work through all the problems in chapters 6,7, and 8 of Zettilli, you will know separation of variables and Frobenius' method for Schrodinger's equation, angular momentum/CG coefficients, and identical particles like the back of your hand.

I actually used Molecular Quantum Mechanics by Atkins as the backup. I liked it so much that soon Griffiths became the backup. :D

I'd recommend you to go through McQuarrie's or Atkins' books even though they aren't for proper physics grads.
