  摘要：

  在转动光谱2 Σ + Cai和BAI的基态已在100 GHz范围内进行了测量。可以从这些光谱中得出精确的邓纳姆系数Y ik和电势常数a i。在解释观察到的γ分裂时必须考虑未解析的超精细结构的影响。

• Steric effects in chemiluminescent reactions of metastable Ca∗, Sr∗ atoms with isomeric propyl halides
  作者：B. Pranszke、P. Kierzkowski、A. Kowalski

  DOI：10.1016/s0009-2614(99)00676-4

  日期：1999.8

  Reactions of metastable alkaline earth atoms with normal and branched propyl halides were studied in a beam-gas arrangement. Chemiluminescence spectra of alkaline earth monohalides were observed for calcium and strontium reactions. Some differences in the CaX () branching ratio were found with isomeric variation of the targets. Total collision cross-sections for Mg∗ and Ca∗ reactions are independent

  在束流-气体装置中研究了亚稳碱土原子与正卤和支链丙基卤的反应。观察到钙和锶反应的碱土金属卤化物的化学发光光谱。发现CaX（）支化比率存在一些差异，这与靶标的异构体变异有关。Mg ＊和Ca ＊反应的总碰撞截面与异构体取代无关。对于锶，异丙基碘的值比正常丙碘靶的值高50％。发现钙与丙碘化物和丙氯的反应在化学发光横截面上存在差异。

  The lifetimes of the A2Π, B2Σ+, C2Π and D2Σ+ states of the CaBr and CaI radicals have been measured directly from the time rate of fluorescence decay using an appropriate pulsed dye laser as an excitation source. The zero pressure radiative lifetimes determined for the first time for the C2Π1/2 state of CaI and D2Σ+ state of CaBr were (50.5 ± 1.5) ns and (21.0 ± 2.6) ns, respectively. The measured

  在A的寿命2 Π，B 2 Σ +，C 2 Π和d 2 Σ +的CABR与CAI自由基的状态已经从使用适当的脉冲染料激光作为激发源的荧光衰减的时间速率直接测量。零压力辐射寿命确定首次用于C 2 Π 1/2 Cai和d的状态2 Σ +分别CABR的状态分别为（50.5±1.5）NS和（21.0±2.6）纳秒。测得的寿命与配体场（LF）模型预测的趋势非常吻合。对于蔡Ç 2 Π 3/2状态（τ = 31.2纳秒在1mbar压力）和d 2 Σ +状态（τ  <11纳秒），异常短的寿命中观察到，表明这些状态预离解。

  The polarization emission of the excited CaI* produced in the Ca(P-3(J), D-1(2)) + CH3I --> CaI* + CH3 reaction has been measured showing evidence for Hund's case (c) in the excited CaI diatom.
