| Description | Extensive quantum chemistry (QC) modeling of new arsenic sulfides identified by TOF MS was performed using Hartree-Fock and density functional calculations with the 6-311G* basis set and electronic energies as well as geometries of positively singly-charged mono-arsenic sulfide clusters were determined. It was found that the cyclic and bi-cyclic structures of AsSn+ (n = 1-7) clusters are more stable than open structures although all are hetero-cyclic. Also the structure of AsS7 is not the expected single-ring AsS7 as analogous to the S8 molecule but it posses a double ring structure with arsenic atom three coordinated. |
