S K-edge XAS Energy Positions (eV) and integrated intensities.

Complex	Pre-edge Energy (eV)^a	Pre-edge Intensity^b	Peak 2 Energy (eV)^a,^c	Peak 2 Intensity^b,^d
1	2469.5	2.13	2470.7	0.51
4	2470.9	1.87	2471.9	1.02
5	2471.1	3.04	2473.0	0.90

Core hole lifetime and instrument broadening ~1.5 eV (full width at half maxima).

The error in total intensity due to data processing and fitting is ±5%.

Peak 2 represents the S 1s → S-S σ^* transition for 4 and 5.

The intensity per S₂ unit.
