∆G°37 coaxial stack =
∆G°37(Continuous Backbone Stack) + ∆G°37(Discontinuous Backbone Stack)
∆G°37 coaxial stack = ∆G°37(AU pair followed by GG mismatch) + ∆G°37(Discontinuous Backbone Stack)
∆G°37 coaxial stack= -0.8 kcal/mol – 2.1 kcal/mol
∆G°37 coaxial stack= -2.9 kcal/mol
∆H°coaxial stack = ∆H°(Continuous Backbone Stack)
+ ∆H°(Discontinuous Backbone Stack)
∆H°coaxial stack = ∆H°(AU pair followed by GG mismatch) + ∆H°(Discontinuous Backbone Stack)
∆H°coaxial stack = –3.5 kcal/mol – 8.46 kcal/mol
∆H°coaxial stack = –12.0 kcal/mol
