Figure 4.
Time-dependent evolution of TRIR bands. (A) Kinetic traces of the excited state decay (1384 cm–1) and the ground-state recovery (1546 cm–1, shown inverted for comparison). (B) Comparison of the rise and decay of radical intermediates in wild-type OaPAC. (C) Comparison of the rise and decay of radical transient at 1528 cm–1 with transient evolving at 1635 cm–1. (D) Kinetic trace of the 1694 cm–1 transient, assigned to light-state formation. Raw data are shown as solid lines or dots, while global fitting results are shown as dashed lines.
