The vibrational modes of a molecule are assigned symmetry labels that tell us something about the symmetry of the vibrational mode. Given the symmetry labels below, specify what each part of the symbol means.
A and E refer to the irreducible representation as being non-degenerate (1D) and doubly degenerate (2D). The "1" and ...
