Adenine-adenine interaction in adenylyladenosine and polyadenylic acid measured with emission spectroscopy.
Dynamical behavior of a melting of stacking interaction in adenylyladenosine (ApA) and polyadenylic acid (polyA) has been investigated with steady state and time resolved emission spectroscopy. Temperature dependence of monomer-like emission and excimer emission shows that the melting behavior of ApA can be analyzed by a simple two-state model whereas that of polyA exhibits the influence of neighboring adenine molecules which can interact in the excited state.
