Extended Data Figure 4: Species-associated difference RDFs of the transient states.
From: Direct observation of bond formation in solution with femtosecond X-ray scattering

The species-associated difference RDFs of the S0, S1, T1 and tetramer states correspond to
,
,
and
, respectively. We used a common S0 structure when fitting all four species-associated difference RDFs. By optimizing the fit between the theoretical and the experimental difference RDFs for each transient species via the structural fitting analysis, we were able to obtain the theoretical RDF of the S0 state.
