Hi,

I am looking at symmetries of phonons at gamma. Since T1u (gamma15) and T2u (gamma25) modes in O_h have the same number of different terms in the character table (same number of '0s' and '1's' etc.) how do I distinguish between them? Is there any way I can write out to what symmetry operation the particular character belongs to ?

Thanks,
Ganesh
