The decomposition of arsine at atmospheric pressure as studied by in-situ and ex-situ Fourier transform infrared spectroscopy (FTIR) is presented, comparing the techniques. Ex-situ spectroscopic and spectrometric evidence for the formation of methylarsine and dimethylarsine during the reaction of trimethylgallium and arsine, and in-situ spectroscopic evidence for the formation of diethylarsine during the reaction of triethylgallium and arsine is discussed. The observation of alkylarsines strongly implies a stepwise free radical reaction mechanism, however whether these processes are heterogeneous or homogeneous remains unclear.The decomposition of arsine at atmospheric pressure as studied by in-situ and ex-situ Fourier transform infrared spectroscopy (FTIR) is presented, comparing the techniques.
