¹H and ¹³C nuclear magnetic resonance data for 1β-OH-DCA, [²H₄]-1β-OH-DCA, and DCA

Chemical shifts are reported relative to the residual methanol signal set to 3.31 ppm (¹H) and 48.7 ppm (¹³C). Chemical shifts for overlapping ¹H signals are taken from relevant two-dimensional experiments. ¹H-Coupling Constants for selected signals are obtained from one-dimensional ¹H- spectra (multiplicity, J Hz).
