6.5 Given that, for 1"c"02: o = 1354.07 cm, w2 = 672.95 cm, w3 = 2396.30 cm, X1 = - 3.10 cm-, x22 = 1.59 cm!,x33 = -12.50 cm-, X12 = - 5.37 cm,x13 = -19.27 cm, x23 = -12.51 cm, %3D %3D g22 = - 0.62 cm calculate the wavenumbers of the v, = 1 level and the vz = 2 (E, = 0) level. The resulting levels both have 2 symmetry and, because of this and the fact that they would otherwise be close together, they interact by a process called Fermi resonance. As a result they are pushed much further apart. (o1, 02, and m, are equilibrium values corresponding to the vibrations v, v2, and v3). %3D
