The acoustical relaxation spectrum of aqueous solutions of oxygenated and deoxygenated hemoglobin solutions was investigated in the frequency range 0.5–1000 MHz. The abrupt high frequency cut off of the broad absorption spectrum is consistent with a heavily weighted, shortest relaxation time of 2 × 10 −9 sec. Both the high‐frequency cut‐off and high frequency residual absorption appear to be slightly different for oxygenated and deoxygenated hemoglobin solution.
