Abstract

Hydrogen bonds are among the most common chemical interactions in condensed phases. Hydrogen bonds also consist of an important part of solute-solvent interactions in solution. These interactions are usually referred to as "specific" solute-solvent interactions. The terminology is used to distinguish between hydrogen-bonding interactions, which are short-range, and solute solvent interactions originating with the dielectric properties of the solvent, which are long-range compared to the molecular graining of the solvent. This chapter focuses on the dynamic aspects of the hydrogen-bonding interaction of some hydroxy-photoacids (ROH). By optically exciting the photoacid, a sudden increase in the acidity of the OH group is induced. The enhanced acidity has caused a sudden increase in the hydrogen-bonding interactions of the photoacid usually of the type O-H-O. The hydrogen-bonding complex (ground state) of the photoacid is prepared in solutions of the photoacid in non-polar solvents and in presence of suitable complexing oxygen bases such as DMSO.
