Individual Reactions

(CAS Reg. No. 14996-02-2 • 4294967295sulphur trioxide) + sulphur trioxide = CAS Reg. No. 14996-02-2

By formula: (CAS Reg. No. 14996-02-2 • 4294967295O3S) + O3S = CAS Reg. No. 14996-02-2

Quantity Value Units Method Reference Comment
Δr103.4 ± 5.5kcal/molN/AWang, Nicholas, et al., 2000gas phase; Lit BDE seems too weak. This plus Viggiano, Henchman, et al., 1992 gives BDE=106
