a
The data involves the net NMR chemical shift (δmax; uncertainty ±0.1 ppm) and fwhm height (W; ±0.15 ppm) of the 31P NMR signal, as well as the chemical shift (δn; ±0.3 ppm), fwhm height (Wn; ±0.5 ppm), and fractional population (xn; ±0.02) of each QPn contribution extracted by spectra deconvolution.
b
Vaules corrected for the NMR-derived minor QP1 contributions.
c
This sample exhibits phase separation and its 31P NMR spectrum required two QP0 signals for deconvolution.
