We sincerely hope that at this point we have made all the possible mistakes that you can make in picosecond IR pump-probe experiments on hydrated protein samples. The last run using a liquid amino acid analog sample (asparagine) indicated that pump-probe signals showing saturation recovery of the amide I band were at the 1% level with 1 μJ micropulse energies. We hope that at FELIX a deep understanding of energy flow and transfer in biomolecules will develop. We are grateful to the patience shown by the FELIX staff, and generous support by the Office of Naval Research Medical Free Electron Laser Program.

N2 - Time-resolved infrared (IR) pump-probe experiments were conducted at FELIX, the free electron laser (FEL) at Nieuwegein, The Netherlands. The study aims to measure the relaxation time, both longitudinal and transverse, of protein molecules at the amide I band and in the far-IR band. To address the problem of high differential sensitivity, the dual element detector approach and the single element approach were applied.
