The present work explores a new phenomenon that not all the transition probability of two photon processes is negligible at low irradiance. The irreducible representation 2B₂ of C_2v is unexpected, for there is no much deviation in oscillator strength for two-photon and single-photon process A₁ to 2B₂. This new phenomenon is only possible to be explored by the symmetrical consideration: the necessary and sufficient condition is molecular plane coincident with yz plane or the operation σ ^’_v(yz) for group C_2v. It is only possible to be evaluated out by use of the full relativistic quantum mechanical theory.
