Polarization resolved vibrational transients of locked Agp1 upon excitation at 713 nm. Signals measured for probe polarization parallel (black circles) or perpendicular (red open squares) to pump polarization. C₁₉ = O stretching vibration in the excited state at 1684 cm⁻¹ and 1688 cm⁻¹ (a), (b),; bleach signal of the C₁₉ = O stretching vibration at 1698 cm⁻¹ (c); C₁ = O stretching vibration in the excited state at 1712 cm⁻¹ (d); bleach signal of the C₁ = O stretching vibration at 1725 cm⁻¹ (e). Biexponential simulations (black and red lines) with time constants of 5.5 ps and 540 ps.
