In this paper, we report the gas‐phase characterization of two differently substituted amino(iminoarsanes), TmpAs=NSiMe 3 and (SiMe 2 t Bu) 2 NAs=N(SiMe 2 t Bu), by coupling flash vacuum thermolysis (FVT) with UV photoelectron spectroscopy (PES). Quantum chemical calculations, using the DFT method (B3LYP) with the basis set 6‐311G(d,p), have also been carried out on the R 1 As=NR 2 unit with R 1 = H, NH 2 , N(CH 3 ) 2 , N(SiH 3 ) 2 and R 2 = H, SiH 3 , in order to study the effect of substitution on the electronic properties and the thermodynamic stability of the As=N skeleton. Similarities with phosphorus analogues are also discussed.
