4. Molecular Quantum Mechanics

4. Math & physics prerequisites

• Linear algebra (operators, eigenvalues/eigenvectors)
• Differential equations (ODEs, separation of variables)
• Complex analysis basics (for integrals)
• Vector calculus (grad, div, curl)
• Basic classical mechanics and electromagnetism
• Introductory quantum mechanics: Schrödinger equation, angular momentum algebra

If any prerequisite is weak: allocate 1–2 weeks to review (Griffiths QM, Sakurai summaries, math methods notes).

6.1. Elastic & Inelastic Scattering

The scattering amplitude (f(\theta)) is related to the S‑matrix via partial‑wave expansion:

[ S_\ell=e^2i\delta_\ell,\qquad f(\theta)=\frac12ik\sum_\ell=0^\infty(2\ell+1)\bigl(S_\ell-1\bigr)P_\ell(\cos\theta) ]

where (\delta_\ell) is the phase shift.

• Differential Cross Section: (\fracd\sigmad\Omega=|f(\theta)|^2).
• Total Cross Section: (\sigma_\texttot = \frac4\pik\Im[f(0)]) (optical theorem).

Collisions, Scattering, and Dynamics

• Elastic and inelastic collisions determine energy transfer between particles.
• Scattering theory (partial waves, phase shifts) predicts cross sections and angular distributions.
• Reaction dynamics: Potential energy surfaces (PES) guide chemical reactions; transition state theory and quantum tunneling explain rates, particularly at low temperatures.

6. Typical chapter checklist (apply to each chapter)

• Read text: 1 pass.
• Re-derive 2–3 main equations.
• Solve 3 worked examples manually.
• Do 5 varied problems from exercises (increase difficulty over time).
• Add concepts/equations to cheat-sheet.
