Chemical Bonding in Diatomic Molecules 14. Molecular Shapes and Energy Levels for Polyatomic Molecules 15. Electronic Spectroscopy 16. Computational Chemistry 17. Molecular Symmetry 主要內容 The Content of the Course

7. The students are expected to have a good command of basic principles of quantum mechanics and how to apply them to solve basic problems important to chemistry, in particular, the theoretical background of atomic and molecular structure and spectra. The students are required to be familiar with the wavefunctions and energy levels of typical quantum mechanical systems such as particle-in-box, vibrator, rotor, hydrogen and hydrogen-like atoms, hydrogen molecule, heteronuclear diatomic molecules. The students will be able to apply group theory to determine the IR, Raman activity of a (simple) molecule or group. The students will learn basic knowledge and skills in doing computational quantum chemistry. 課程目標 Objectives of the Course

8. This course requires students to have taken basic and advanced calculus (including differential equations), matrix algebra, point group theory as well as general physics (classical Newtonian mechanics and electromagnetism). 特別提醒：此課程有較強的數學和物理的預備要求： 高等微積分（含微 分方程），矩陣代數，點群理論，普通物理學（力學，電磁學），如這 些方面有問題，請在修課前儘早補習，並及時接受輔導。 請好好利用課程網頁的資料： http://140.117.34.2/faculty/phy/sw_ding/pchem1-00.htm （含講義投影片， 作業，答案，參考資料等。請修課同學下載並盡量多花時間閱讀。） 另外，每禮拜我將提供 2-4 小時的數學及物理的補習及答疑，請在數理方 面感到有困難的同學盡量多參加。

12. A quick tour of the history of quantum chemistry (up to 1940) Greek atomic theory Dalton’s atomic theory Arrhenius’ ions Thomson’s electron Rutherford’s nucleus Planck’s quantum Einstein’s photon Bohr’s model de Brodgile’s wave Schrodinger’s wave equation Heisenberg’s observables and uncertainty principle Pauli’s exclusion principle Heitler-London’s hydrogen molecule Pauling’s chemical bond Herzberg’s molecular spectra

13. 沒人睬我 一尺之棰 日取其半 萬世不竭 莊子

14. Ancient Greeks Matter cannot be divided infinitely; there should be a limit beyond which matter cannot be further broken. ATOM – unbreakable.

16. Democritus as right; Aristotle was wrong!

17. Svante Arrhenius: Dalton theory is flawed + - But I really did not know what is an ion

18. Thomson: Arrhenius was right, atoms do have structure! I now what Arrhenius’ ions mean

19. Ernest Rutherford: the atoms are mostly empty! The electrons and nucleus in the diagram are enlarged. A real atom is much more empty than this!

20. Electrons may be used as best ‘light’ to see tiniest possible things!

21. Niels Bohr: atoms are a tiny solar system I can explain these colors Quantum Transition

22. Erwin Schrodinger: I can calculate the spectrum of hydrogen atom Sorry, the law for microscopic objects is a little bit more complex than F = ma!

23. Werner Heisenberg ： only observables are meaningful in microscopic world; no ‘reality’ before measurement Any physical quantity must be treated as a differential operator (or matrix). Simultaneous measurements of two physical quantities may interfere with each other, leading to uncertainties:

24. Wolfgang Pauli: Electrons are Fermion Electron is bizarre; a pair of electrons is insane. One electron is fun; a pair of electrons is ecstasy.

25. This table tells us that our world at the fundamental level is quantum mechanical. Periodicity is a consequence of quantum mechanics. The ‘shell and subshell’ turned out to correspond to the physical quantities we can possibly measure of an atom (good quantum numbers)

26. Organic Chemistry Depends on Covalent Bonding. Without Covalent Bonding, There’d be no Organic Compounds. Covalent Bonding Had Been Very Mysterious Before 1927. Formed between two neutral atoms Saturation Directionality Resonance/Hybridization Etc. All these make no sense in classical physics!

27. Walter Heitler, Fritz London: hydrogen molecule exists, thanks to quantum mechanics. God modified the law in microscopic world so that molecules can form.

28. Linus Pauling ： I understand covalent bond. Organic chemistry would not have existed had the microscopic world obeyed Newtonian o Maxwell Laws.

29. Herzberg ： molecular vibration and rotation tell us a lot Electronic ground state Vibrational state Electronic first excited state Energy Nuclear Coordinate

31. The objectives of quantum chemistry The structure of atoms and molecules The dynamics of molecules The interactions between molecules It has achieved tremendous progress but it is still developing.
