My technique for constructing MO diagrams is based on (and significantly simplified from) that of Verkade. While I find it works well in my classroom for my students, they benefit from careful step-by-step instruction of the method through several weeks of in-class exercises. This LO has links to pencasts where I go through three easy examples that demonstrate the technique, as well has how I handle lone pairs by this method. As transition metal complexes don’t have stereochemically active lone pairs, they are often easier to deal with than even something seemingly as simple as water!
by watching these pencasts, instructors or students should be able to use my generator orbital method for constructing LGOs and MO diagrams.
to watch the pencasts, you need an internet connection, but the software is hosted at the website.
update, Summer 2015: The Livescribe website has changed. Now, you create a PDF with your livescribe pen, and that PDF can be played at the livescribe website (www.livescribe.com/player). I have converted my old pencasts to playable PDFs and attached them to this LO.
