Collision-induced transitions of NH/sub 3/ in the collisions with He and H/sub 2/ are studied by the laser-microwave double and triple resonance methods. The results are summarized in the preference rules. It is confirmed that ..delta..k= +- 3n transitions occur, while ortho-para conversion is still strictly forbidden.
