摘要

The authors have obtained rotationally resolved vacuum ultraviolet pulsed field ionization-photoelectron (vuv-PFI-PE) spectrum of HD in the photon energy range of 15.29-18.11 eV,covering the ionization transitions HD+(X2SIGMA_g~+,v+=0-21,N+)<-HD(X1SIGMA+g~+,v" =0,J").The assignment of rotational transitions resolved in.the vuv-PFI-PE vibrational bands for HD+(X2SIGMA_g~+,v+=0-20) and their simulation using the Buckingham-Orr-Sichel (BOS) model are presented.Rotational branches corresponding to the DELTA N=N+-J"=0,+-1,+-2,+-3,and +-4 transitions .are observed in the vuv-PFI-PE spectrum of HD.The BOS simulation shows that the perturbation of vuv-PFI-PE rotational line intensities due to near resonance autoionization is very minor at v+ >=5 and decreases as v+ is increased.Thus,the rotationally resolved PFI-PE bands for HD+(v+ >=5) presented here provide reliable estimates of state-to-state cross sections for direct photoionization of HD,while the rotationally resolved PFI-PE bands for HD+(v+<5) are useful data for fundamental understanding of the near resonance autoionizing mechanism.On the basis of the rovibrational assignment of the vuv-PFI-PE bands,the ionization energies for the formation of HD+(X2SIGMA_g~+,v+=0-20,N+) from HD(X 1SIGMA_g~+,v"=-0,J") and the vibrational constants (omega_e,omega_ee,omega_ey_e,and omega_ez_e),the rotational constants (B_e and alpha_e),the vibrational energy spacings,and the dissociation energy for HD+(X2SIGMA_g~+) are determined.As expected,these values are found to be in excellent agreement with high level theoretical predictions.
