2-Cyanophenol (2CP) solutes form two-types of hydrogen bond in aprotic polar solvent. The complexes simultaneously in that 2CP hydroxyl has intra-molecular hydrogen bond and unusual forms are inter-molecular hydrogen bond with neighboring 2CP molecule when they are dissolved in dichloromethane and chloroform. This can be viewed as a simple prototype model system for a Watson-Crick base pair formation. Thus, studying such a cyclic dimer formation process in the condensed phase will provide us with information on the time scale and mechanism of the hydrogen-bonding dynamics. So we are trying to carry out 2D-IR chemical exchange experiments to study possible dimer formation-dissociation dynamics of certain 2CPs in a polar aprotic solvent. Also, the vibrational anharmonic frequency shifts, intrinsic lifetimes, and bandwidths of the nitrile stretch mode and the combination mode in these molecular systems are fully characterized, and their relationships with resonance structures are discussed.
