Abstract:
Using stimulated Raman pumping the angular momentum of molecules in a vibrationall excited state can be oriented.Linear molecules like acetylene can be prepared with rovibrational state selectivity with an orientation parameter of A0(1)=0.7 to 0.8.The rate con-stants of Orientation decay have been also at first time measured.
Key words:  Stimulated Raman pumping,Angular momentum orientation,Collision decay

分子角动量定向布居的制备探测和它的碰撞弛豫
高文斌,A.D.Rudert,J.Martin,H.Zacharias,J.B.Halpern
摘要:
利用受激Raman泵浦,使线性分子C2H2选择性地制备振动态角动量定向布居参数A0(1)达到0.7~0.8。并测定了角动量定向布居碰撞诱导的弛豫速率常数。采用园偏振的紫外激光诱导荧光方法,可表征分子角动量定向布居的制备和它的碰撞弛豫过程。
