TABLE V.

Standard deviations of conformational parameters determined from H–F model analyses of absorbance, CD, and 2DFS data of (iCy3)₂ dimer-labeled ss–dsDNA fork constructs. The optimized values were obtained by minimizing the least squares error function ${\chi }_{2DFS}^2$ described in Sec. III D, which are shown in Fig. S23 of the supplementary material.
