1. The problem statement, all variables and given/known data
Determine the point group of the chair conformer of cyclohexane. How many Raman active vibrations and how many infrared active vibrations might you expect to detect in its spectrum? 2. Relevant equations (see link below) 3. The attempt at a solution http://img442.imageshack.us/img442/240/symmetrycw.jpg Im rubbish with LaTex so ive hosted a picture of what ive done in word. Ive determined the point group to be D3h but when I use the equation to get the values for the different vibrations, I get a total of 24 when it should be 18 because I started with 18 vectors (3 on each carbon). Im not sure where im going wrong. Thanks.
