Picosecond absorption spectroscopy is used to examine the position and band shape of the near infrared absorption band of hemoglobin as a function of time after the photodissociation of CO from carbonmonoxyhemoglobin. For the earliest delay time probed, 35 ps, the peak of the transient spectrum is at 765 nm, red shifted by 6 nm from that characteristic of equilibrium deoxyhemoglobin. No evolution in either the peak position or band shape is observed for time delays up to 60 ns. In addition, the position and shape of the spectrum are independent of photolysis energies ranging from 15 microJ/pulse to 150 microJ/pulse, spanning conditions under which the photon/heme ratio is varied from 0.01 to 2.0. This indicates that the geometry in the heme group is unrelaxed and that equilibration of the surrounding protein structure occurs on a time scale longer than 60 ns.
