Perpendicular quadrupolar splitting, ΔνQ⊥, as a function of temperature. (◆) d54-DMPC, (■) VDAC1/d54-DMPC 2D crystal. ΔνQ⊥ were difficult to determine with precision at lower temperatures due to poorer signal-to-noise ratio caused by spectral broadening in the gel phase. ΔνQ⊥ were reproducible to within 5% (d54-DMPC) and 10% (VDAC1/d54-DMPC) for these spectra.
