Abstract

We show that myoglobin, which is almost entirely α-helix in secondary structure, has an unusually long-lived 12 ps vibrational excited state lifetime generated by optically pumping at the blue side (5.85 microns) of the amide I band, indicating the generation of a long-lived trapped soliton-antisoliton breather mode.
