Canonical Watson-Crick base pairs and four representative mismatched base pairs have been studied by quantum chemical computations. Detailed anharmonic vibrational analysis was carried out to reveal some vibrational s...
We present quantum mechanical vibrational computations beyond the harmonic approximation from effective second order perturbative and variation perturbation treatments defined as static approaches, as well as vibratio...
V. ACKNOWLEDGMENT This work was supported by the National Natural Science Foundation of China (No.20773136 and No.30870591), the National High-Tech Research and Development Program of China (No.2007AA02Z139), and the Hundred Talent Fund of the Chinese Academy of Sciences.
Changes of molecular structure and associated charge distributions, and changes of anharmonic vibrational parameters from DNA base monomers to the Watson-Crick base pairs, have been investigated at the density functio...
