Stability of the tin analogues of isocyanic acid, [HNSnO], and its isomers: a computational study

Here we report the detailed potential energy surface (PES) for the singlet and triplet isomers of [H,N,Sn,O] using the DFT-based B3LYP method and the LANL2DZ basis set. The PES reveals a lot of stationary states thus indicating the possible existence of stable species. The barriers for isomerization and dissociations for these have been calculated and they ascertain the stability.
