  with those forecast by DFT calculations. Photoexcitation at λ = 200−400 nm results in insertion of the group 13 metal atom into a C−H bond to form the angular monomethylmetal hydride molecule, CH3MH (M = Ga, In). This product is not photostable but decomposes on exposure to radiation with λ = 200−800 nm to give the first sighting of CH3M, the simplest organic derivative of Ga(I) and In(I) to be characterized

  IR和UV / Vis光谱测量已用于通过照射含镓或铟原子的甲烷掺杂氩气矩阵来制图设定的反应，首先用λ= 200-400 nm的光，然后用宽带UV-可见光辐照光。根据D和13 C取代，并与相关分子的振动特性或通过DFT计算预测的振动特性进行比较，对IR吸收带进行了分配，并对其载体进行了表征。在λ= 200-400 nm处进行光激发会导致第13组金属原子插入C H键中，形成有角一甲基金属氢化物分子CH 3MH（M ＝ Ga，In）。该产物不是光稳定的，但是在暴露于λ= 200-800 nm的辐射下会分解，从而首次发现CH 3 M，这是迄今为止表征的最简单的Ga（I）和In（I）有机衍生物。将CH 3 MH和CH 3 M物种的振动特性与相关分子的振动特性进行比较，并分析它们发出的具有Mc和MH键特征的光。

  The metal alkyls trimethylaluminum (TMA), trimethylgallium (TMG) and trimethylindium (TMI) were decomposed under collision-free conditions by tunable UV laser light in the range 190-310 nm and the photoproducts detected by laser mass spectroscopy using short and ultrashort laser pulses. At moderate laser fluences, these compounds decompose via a one-photon process. The simple separation of one or two methyl ligands leads to the metal-dimethyl radical (Al(CH3)2, Ga(CH3)2, In(CH3)2), and the metal-monomethyl radical (AlCH3, GaCH3, InCH3) as photoproducts. The vibronically excited metal-dimethyl radical can further decay - without the absorption of additional photons - into the metal atom plus ethane molecule. This has been proved for the first time by laser mass-spectroscopic detection of the ethane molecule as being a direct photoproduct of the investigated trialkyls. The quantum yields for the wavelength-dependent fragmentation are presented.

  curves of trimethylindium were recorded at different heating rates and crucible loading densities. The two dominating exothermic bands were kinetically analysed by fitting a two-step reaction model of first-order to the deconvoluted DSC data. The kinetic parameters, calculated at low loading densities, are log z 1 = 18.3 ± 0.2 s −1 , E 1 = 215.4 ± 0.8 kJ/mol and log z 2 = 9.3 ±0.2 s −1 , E 2 = 139.2 ± 0
