Hi everyone,
I have a question regrading symmetry operations.
In determining the IR/Raman spectra for XeF4 using the symmetry operation for point group D4h, I was generating the irreducible representations (IRR). For the B1g IRR, I get 1/2 in which I do not understand what it means? I assumed all the IRRs should be whole integers. I get fraction values for the other B IRRs but not for the A or the E IRRs for this point group.
Really appreciate it if anyone can give advice on this probem.
Thank you.
