  摘要：

  每周结合的复合物的振动预离解和电子猝灭动力学已使用激光诱导的荧光和分散的荧光进行了检查。我们发现预解离发生在⩽1ps的时间尺度上，与水平相关的复合物的制备。此外，我们建议它描述了去除人口简单的动力学分析和OHN没有荧光的2级水平由约束势能面。该机理暗示非绝热衰变，即猝灭，对于这些络合物可能是重要的。

  The intermolecular vibrational energy levels supported by the OH A 2Σ+ (v′=0,1)+N2 potentials have been characterized spectroscopically through excitation of OH–N2 complexes in the OH A 2Σ+–X 2Π 0–0 and 1–0 spectral regions. At least 95 levels correlating with OH A 2Σ+ (v′=0)+N2 are observed in fluorescence depletion experiments. OH–N2 complexes prepared in these levels have lifetimes with lower limits ranging from 1.4 to 8 ps due to rapid electronic quenching which precludes their detection by laser-induced fluorescence. An onset of OH–N2 laser-induced fluorescence occurs at the OH A 2Σ+ (v′=0)+N2 dissociation limit, enabling determination of the ground and excited state binding energies at ∼250 and ⩾1372 cm−1, respectively. In the OH A–X 1–0 region, OH–N2 transitions originating from a common ground state level to single or groups of intermolecular vibrational levels correlating with OH A 2Σ+ (v′=1)+N2 are observed via laser-induced fluorescence and fluorescence depletion measurements. Comparison of the OH–N2 spectra obtained in the OH A–X 0–0 and 1–0 regions reveals that vibrational excitation of OH A 2Σ+ increases the OH–N2 binding energy by 139 cm−1. OH–N2 complexes excited in the OH A–X 1–0 region undergo ultrafast dynamics (&lt;200 fs) which give rise to extensive spectral line broadening. A kinetic model indicates that vibrational predissociation is the dominant decay channel for OH–N2 prepared in the intermolecular levels derived from OH A 2Σ+ (v′=1)+N2.
