| 英文摘要 | 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 functional theory level. through examination of the nh(2), n-h, and c=o stretching vibrational modes that are involved in the multiple h-bonds in the base pairs, sensitivity of their diagonal and off-diagonal anharmonicities, as well as anharmonic vibrational couplings, to the structure change are predicted. our results reveal the intrinsic connection between the anharmonic vibrational potentials, h-bonding, and electrostatic interactions in dna bases. |
