Figure illustrates the T1-T2* correlation plots throughout several stages of the reaction pathway i towards the synthesis of 1. There are two methods to process T1-T2* data of solid-like samples. The simpler method is to process data by presuming the T2* decay is exclusively exponential. This provides qualitative data but is not appropriate for quantitative analysis, though is the most straightforward with some mathematical assumptions. The non-exponential processing method developed by Guo et al. provides quantitative results by processing the non-exponential parts of the decay separate from the exponential decay. Correlation plots in Figure -d show the results using exponential processing, while the plots in Figure -h used non-exponential processing. The T1-T2* plots of benzil (Figure and Figure ) are identical since the captured benzil signal decays exponentially, it does not contain a non-exponential region. The plots are all scaled equally, to an intensity value of 1000, to provide quantitative comparison between the samples. All samples were measured at reaction scale. Each plot is described below, with only major or important peaks defined. All major peaks are listed in Table , it should be noted that the relaxation time values of exponential processing are very similar to non-exponential processing.
