Time constants resulting from global fits of datasets of p(SQ-R^2*) in acetone shown in Fig. 7a and c and in the ESI, Section S3, Fig. S6b are compared to time constants obtained from TA measurements in DMF previously⁵⁵.

Dataset	τ 1	τ 2	τ 3	τ 4
TA (ref. 55)	100 fs	2 ps	8.6 ps	43 ps
TA (this work)	—	814 fs	19.8 ps	171 ps
TRCD (direct)	—	966 fs	—	140 ps
TRCD (achiral data subtracted)	—	1.05 ps	—	202 ps
