FIGURE 4.

EADS of R26 RCs lacking Q_A calculated from measurements carried out over a broad spectral range between 2280–1600 cm⁻¹. The spectra between 2153–2075 cm⁻¹ are not shown due to the high IR absorption by D₂O in this region. The lifetimes shown are the result of global analysis of the data obtained in 1780–1600 cm⁻¹ region (Fig. 2). Excitation was at 600 nm in each case.
