Interpretation of CD spectra for conformers I, II, and III for 22-mer PMO
Shown are the theoretical CD profiles (black solid lines) for conformer I (A), conformer II (B), and conformer III (C). Each of these profiles has been broken down into CD spectra calculated separately for the two halves of each conformer, shown structurally in the panels’ insets, for bases 1–11 (red solid lines) and for bases 12–22 (blue solid lines). The experimental CD profile for 22-mer PMO in water is shown via black data points. The four vertical dotted lines are placed at wavelengths corresponding to peak maxima and trough minima to aid in the visual comparison of all the CD curves.
