title: DNA solution conformation via infrared circular dichroism: experimental and theoretical results for B-family polymers.
abstract: Infrared (vibrational) circular dichroism (VCD) has been observed for the DNA models d(CG)5, poly(dG-dC).poly(dG-dC), poly(dG).poly(dC), poly(dA-dT).poly(dA-dT), and poly(dA).poly(dT) in the B-conformation in buffered, aqueous solution. The observed results are quantitatively interpreted in terms of the exciton model for coupled carbonyl stretching vibrational states.
