| temp (K) | ΔG (cal/mol) | ΔH (cal/mol) | ΔS cal/mol K | ΔSnp cal/mol K | ΔSpe cal/mol K | number of water release = ΔSnp/5.27 |
|---|---|---|---|---|---|---|
| 288 | –7757 | –615 | 24.80 | 18.04 | 6.76 | 3.42 |

All the free energy changes (ΔG), enthalpy changes (ΔH), and entropy changes (ΔS) in this table are derived from the ITC study. The values of the polyelectrolytic entropy changes (ΔSpe) are determined from the absorbance study using the relationship ΔSpe = ΔGpe/T. Nonpolyelectrolytic entropy changes (ΔSnp) are determined using the equation ΔSnp = ΔS – ΔSpe at given temperate.
