(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I need help assigning the peaks in a Raman spectrum of acetylene(ethyne).

The peaks are :

Wavenumber Contours

3372 OQS

1973 OQS

613 OPRS

2. The attempt at a solution

Ethyne has 7 vibrational modes ( with two degenerative modes)

It has a point group of d infinity h

I dont see how I calculate the reducibile representitive because its an inifinity group, the order of the group will be infinity for a start.

All help is greatly appreciated , thanks!
