Table 2. ³¹P NMR Data for Paraoxon-Gd₃N@C80(OH)_n Fullerene Interactions^a.

[Gd₃N@C80(OH)_n] (M)	Gd:paraoxon ratio	δ (ppm)	Δδ (ppm)
0.0 × 10	0	6.49	N/A
3.6 × 10^–3	2:1	6.71	0.22
9.0 × 10^–3	10:1	6.97	0.48

Δδ (ppm) represents the observed chemical shift (δ) change for that specific fullerene-containing sample vs the δ observed for the paraoxon control.
