Abstract
The rotational angular momentum orientation of acetylene in vibrationally excited discrete rotational state (X1Σ+g，ν″2＝1，J″) has been selectively prepared by circularly polarized laser stimulated Raman pumping. From the induced fluorescence by a circularly polarized UV laser, A1Au(ν′3＝1)←X1Σ+g(ν″2＝1), the orientation of C2H2(X1Σ＋g，ν″2＝1，J″＝4，7，8，…，13）is measured for the first time. The decay rate constants and transfer of the orientation from the initial excited level to neighboring rotational states have been extracted.
