本文用Ca或Sr金属蒸气与Hg(CH3)2及其它几种含CH3的氧化剂气相反应，观察了有机金属自由基CaCH3和SrCH3的生成。确定了A 2E-X 2A1和B 2A1 - x 2A1跃迁的位置，以及几个振动频率。在a2e状态下预解离的观察结果表明，CaCH3 （SrCH3）的键解离能上限为46 kcal/mol （43 kcal/mol）。
We have observed the organometallic free radicals CaCH3 and SrCH3 by the gas phase reaction of Ca or Sr metal vapor with Hg(CH3)2 and several other CH3 containing oxidants. The positions of the A 2E–X 2A1 and B 2A1–X 2A1 transitions were determined, as well as several vibrational frequencies. The observation of predissociation in the A 2E state gives an upper limit of 46 kcal/mol (43 kcal/mol) to the bond dissociation energy for CaCH3 (SrCH3).
