| 摘 要： | 本文首次测定了ＯＣＳ分子在２９９～３０２ｕｍ波段的多光子电离谱。这一段的谱线被归属为Ｄ１Σ＋←Ｘ１Σ＋的跃迁。通过激光功率和离子信号强度的关系，认为ＯＣＳ分子多光子电高经历了（２＋１）三光子电离的过程。此外，还考察了ＯＣＳ的压力对离子信号强度的影响，并对此进行了讨论。

| Abstract: | The REMPI spectra of OCS molecules in the region of 299-302 urn are reported. The main spectral bands have been assigned to D Ic+-X Ic+transition. The power dependence shows that the signal of REMPI results from two-photon resonant, threephoton ionization.The pressure dependence of OCS has been measured, and the results discussed. |
