Figure 6.

Interpolated w_Xxx[T] values assigned from the chemical shift-derived relative helical propensities w_Xxx/w_Ala of Figure 5 by w_Ala[T] multiplication followed by T-dependent quadratic fits as detailed in the Supporting Information. The depicted curves for w_Ala[T], w_Nva[T], w_Gly[T], and w_Pro[T] have been reported previously.¹³ See this report for a discussion of the problems that attend accurate assignment of w_Pro[T] at low temperatures.
