The symmetry labels of three normal modes of water are Γ1 = A1, Γ2 = A1, and Γ3 = B2. The polarization of light required for overtone [(0,0,0) to (0,0,3)] and combination [(0,0,0) to (1,0,1)] transitions, respectively, are [The symmetry of dipole moment operators μx, μy, and μz, respectively, are Γμx = B1, Γμy = B2, and Γμz = A1]:
