N2 - The operator for interaction between a monochromatic electromagnetic field (light) and molecules is usually presented as two multipolar series expansions V E1 +V E2 +…(electro-dipole, electro-quadrupole,…) and V M1 +V M2 +… (magneto-dipole, magneto-quadrupole, …). The optical transition probability is proportional to the complex square of the sum of these series, which contains interference terms like V En V En ′ ,V Mn V Mn′ , and V Ep V Mk (n≠n ′ ). In the present study it is shown that all of the terms V Ep V Mk may be observed experimentally if the molecules are oriented, electrically and magnetically, and the light with appropriate phase shift between electric and magnetic fields is used. Also, a simple operator for the light-molecule interactions is proposed as an alternative to the Taylor series mentioned above.
