文摘
- •
B values are positive for nucleic acid bases and nucleosides in aqueous GnHCl.
- •
Standard molar enthalpy of transfer is exothermic.
- •
Transfer parameters support the strengthening of hydrophilic–ionic interactions.
- •
Loss of π–π∗ maxima of solutes at higher molalities of GnHCl.
- •
Increased concentration of GnHCl leads to formation of plateau at 230 nm.
