Abstract
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 2B 2 of C 2v is unexpected, for there is no much deviation in oscillator strength for two-photon and single-photon process A 1 to 2B 2 . 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.
