However, the extremely broad peaks precluded a conclusive assignment to a specific distortion. Vibrational spectroscopy offers a unique possibility to eliminate, or at leastreduce, the influence of dynamic processes, since the timescales involved are extremely short.

If you are trying to look for potential mixing of orbitals in the lowered symmetry, then you have to look what the irreps in the lowered symmetry are. Good communication in science has to be precise and clear! This tells you that if you decrease the symmetry of the system from $O_\mathrm h$ to $T_\mathrm d$, then anything that previously transformed as $\mathrm{A_{1g}}$ will now transform as $\mathrm{A_1}$.

A mountain swallowtail butterfly has only a mirror that cuts through the head, thorax, and abdomen. While a point group contains all of the symmetry operations that can be performed on a given molecule, it is not necessary to identify all of these operations to determine the molecule's overall point group. Well, I got it from this diagram in Orbital Interactions in Chemistry, 2nd ed. The correct answer is Option A. XeF 6 +3H 2 OXeO 3 +6HF XeF6 is one of the three binary fluorides formed by the xenon. Very sophisticated coupled-cluster calculations (CCSD(T)-F12b) were carried out by Peterson et al., and led to the conclusion that the $C_\mathrm{3v}$ structure was the ground state.13 The eight equivalent $C_\mathrm{3v}$ structures (an octahedron has eight faces) underwent interconversion via $C_\mathrm{2v}$ transition states $\pu{1.08kcal/mol}$ higher in energy.
