where we define the b-V energy, ∆ t E b,V ≡ ⟨V b,V ⟩ 1 , and define the a-V reorganization energy, ∆ t E a,V ≡ ⟨V h,V ⟩ 1 -⟨V a,V ⟩ a , which quantifies the change in the a interactions with the solvent due to restructuring the solvent around the solute after turning on the b-V interactions. We also define the (internal) solute reorganization
