    Excerpt: ... Chemistry 475 Reinhardt and Cooksey Autumn 2001 No homework due Wednesday the 21sthave a good holiday! Assignments and Sets 19 (repeated) and 20. Set 19 due Monday, Nov 26th NOTE this assignment is from McQ and Simon Physical Chemistry not McQ Quantum Chemistry. In McQuarrie and Simon Read Chapter 13, pp 495 to 504. This discusses the spectrum of a vibrating and rotating diatomic molecule . This will be the subject of lecture on Wednesday Nov 21. Homework set #19 is based on this reading. WORK problems 13-10 and 13-12 from McQuarrie and Simon NOW back to McQ, quantum Chemistry Assignment 20: Read McQ Ch 6 Sections 6-8 through 6-10 on the H atom. Review the discussions on spherical harmonics as needed. We will be discussing these extensively, again. A good summary appears in Tables 6-5 (page 224) and in Table 6-6 on page 238be sure to understand what is going on here! The functions in Table 6-5 are simultaneous eigenfunctions of H, L2 an Lz, while those of 6-6 are their real linear co ...

    Excerpt: ... ton Mifflin Company.All rights reserved. Presentation of Lecture Outlines, 1014 Molecular Orbital Theory Valence bond theory does extremely well for most simple molecules. However, there are certain complex molecules for which a more complete theory, called "Molecular Orbital Theory", works much better. Even for diatomics such as O2, there are significant problems with valence bond theory that molecular orbital theory can fix easily. The main problems have to do with the prediction of magnetic properties, and specifically the presence of paramagnetism in diatomic molecule s with a total of 12 valence electrons (such as O2). Copyright Houghton Mifflin Company.All rights reserved. Presentation of Lecture Outlines, 1015 Molecular Orbital Theory Diatomics with a total of 12 valence electrons would be predicted to have electron-dot structures with a double bond (4 valence electrons) and 2 lone pairs on each of the 2 atoms (for a total of 8 electrons in lone pairs). All of the electron ...
