Experimental ²H relative signal intensities, relaxation, and correlation times for the β and γ water components in purified porcine aortic elastin at 37°C

	Untreated sample	Glucose-treated sample
γ component
$T_1$ (ms)	$107.20\pm 13.90$	$117.70\pm 11.50$
$T_2$ (ms)	$20.44\pm 2.20$	$29.67\pm 6.43$
${\tau }_{\text{c}}$ (ns)	$11.35\pm 2.00$	$9.00\pm 2.65$
β component
$T_1$ (ms)	$163.00\pm 33.30$	$163.00\pm 33.30$
$T_2$ (ms)	$36.36\pm 7.54$	$50.08\pm 8.75$
${\tau }_{\text{c}}$ (ns)	$9.95\pm 3.50$	$7.55\pm 2.85$
Signal intensity per unit dry sample mass (AU/g)
$\gamma +\beta$	1.18	2.32
γ	0.43	1.15
β	0.75	1.17

Correlation times were determined using Eqs. 6 and 7. The uncertainties are determined from the distribution in the $T_1$ - $T_2$ map. The table also includes the signal intensity of each reservoir and the sum of the intensity in γ and β, determined from the integrated area in the two-dimensional ILT map per unit dry sample mass (AU/g). See Fig. 5 for denotation of β and γ water components.
