Abstract
Transient infrared absorbance changes of photolyzed carbon monoxide are used to probe internal dynamics in myoglobin over the time range 50 ns to 10 \ensuremath{\mu}s and the temperature range 100 to 240 K. The infrared absorbance of the photolyzed carbon monoxide at temperatures above 170 K disappears long before the CO recombines with the iron, indicating that the carbon monoxide experiences substantial time-dependent heterogenous line broadening. We argue that this broadening occurs as the carbon monoxide diffuses a substantial distance from the heme iron binding site.
