As noted, plots for benzil (2a and 2e) are identical and placed in a row to better visualize the development of the reaction using exponential and non-exponential processing. The two major peaks have T1 values of 0.12 s, and 91.4 s, and both have a T2* value of 10 µs (Figure and 2e peaks B and C on both plots). The very long observed T1 value is a typical feature of a solid-state chemical sample.
