a, 2DES spectrum at T = 10 ps. b, Amplitude transients sampled at the marked coordinates in the 2DES spectrum with a transient fitted over the T > 40 fs range (solid black curve) composed of two exponential components, A(T) = a0 + ∑i ai exp(−T/τi), convoluted with a 12-fs Gaussian instrument-response function. For the diagonal (16.5,16.5) transient: a0 = −0.24, a1 = 4.9, τ1 = 1.4 ps, a2 = 9.8, τ2 = 38 ps; for the ESA transient (16.5,14.9): a0 = 3.2, a1 = −6.6, τ1 = 180 fs, a2 = −16, τ2 = 23 ps. The bars indicate 95% confidence intervals for the amplitudes. The delay T axis is semilogarithmic, with the linear/log split at 100 fs.
