Irreducible representation for C3 point group
« on: February 13, 2020, 03:18:04 PM »
Hey!

I am a college student working on an app to help chemistry students get the solution to a point group. Similar to the webpage, http://gernot-katzers-spice-pages.com/character_tables/index.html .

I am currently having trouble get the solution for certain group points such as: c3, c4, c5, and c6.
When I go about inputting [24, 0] for c3 in my app it gives me the value of 8A + 16E, but the correct answer is 8A + 8E.

I use the given table in http://gernot-katzers-spice-pages.com/character_tables/C3.html , to calculate the answer. This is how I go about solving it.
 =  coefficient * table value * input
A = 1 * 1 * 24 + 2 * 1 * 0 = 24 / h = 24 / 3 = 8 A
E = 1 * 2 * 24 + 2 * -1 * 0 = 48 /h = 48 / 3 = 16 E

I was wondering if anyone here could possibly show me a step by step solution on how to get the correct answer?
