Experimental data highlighting the growth and subsequent decay of the DQF signal of deuterated water in elastin. In these experiments the double quantum evolution time δ was set to 15 μs while τ was varied over the range noted on the horizontal axis. The experimental results shown here were collected with the temperature increasing starting from −15 °C. The solid line is a best fit to the experimental data based in Eq. (6).
