title: Probing electronic coupling between adenine bases in RNA strands from synchrotron radiation circular dichroism experiments.
abstract: Circular dichroism spectra (176-330 nm) of RNA adenine oligomers, (rA)(n) (n = 1-10, 12, 15, and 20), reveal electronic coupling between two bases in short strands. The number of interacting bases in long strands is more and larger than that reported previously for the corresponding DNA strands.
