The vibrational quantum number 0 corresponds to the ground state, 1 to
$\nu_6=1$ (Out-of-plane in phase CH bend), 2 to $\nu_5=1$ (Out-of-plane
out of phase CH bend), 3 to $\nu_3=1$ (symmetric CC stretch + in-plane
symmetric CC stretch), and 4 to $\nu_2=1$ (C=C stretch).
	
The dipole moment was measured by: H. Kanata, S. Yamamoto and S. Saito,
1987, Chem.\ Phys.\ Lett.\ {\bf 140}, 221.
