How much detail do you go into when discussing symmetry planes in C4v molecules? There appears to be a semi-consensus that the vertical (σv) planes should contain as many atoms as possible, with the second set of planes (σd) bisecting the first.
As I begin my 19th year of teaching I realize that I do not have a good grasp of group theory or how to formally use it to determine the number of IR active vibrations in a species. I am trying to come up with a good exercise for my students that could introduce them to point groups and character tables.
I teach a one-semester upper-division course where, as we all know, tough decisions need to be made. I have always taught symmetry, but it has become apparent that our students enter their senior year weak in kinetics, so I am considering swapping out symmetry/group theory for a more advanced treatment of kinetics and mechanisms. This pains me, because these two topics are are two of my favories. Then again, so is everything else...
I am teaching a thrid year inorganic course and want to teach some IR basic using symmetry and character tables.
I would like to go over generating Reducible representations and then use the reduction formula based on the character table to get to the irreducible representation.
I am using Housecroft and Sharpe's Inorganic Chemistry Text book, 3rd edition and they do cover this topic a little bit, biut I was wondering if anyone knows of other more comprehensive resources with further examples and explanations.
