Figure 6.

Polarization resolved vibrational transients of the C₁₉ = O bleaching signal upon excitation of locked Agp1 at 713 nm and 644 nm. Signals for parallel polarization (black dots and gray open squares) are scaled to follow the same dynamics for long delay times. The signals for perpendicular polarization (green open circles and red squares) are clearly separated in amplitude. Biexponential simulations (solid lines) with time constants of 5.5 ps and 540 ps.
