The presence of unpaired electrons in deoxyhemoglobin and hemosiderin gives them paramagnetic properties which produce a nonuniform magnetic field and a rapid dephasing of proton spins, resulting in a loss of signal best seen on SWI.

Susceptibility-weighted Imaging in Thrombolytic Therapy of Acute Ischemic Stroke

It is possible to separately quantify the relative amounts of the reduced and oxidized forms of hemoglobin or cytochrome oxidase by using two measurement wavelengths (typically 760-780 nm for deoxyhemoglobin and 825-850 nm for oxyhemoglobin) at which the two forms have different absorption coefficients.

Macromolecular crystallography and structural biology databases at NIST

Near-infrared rays of dual wavelengths (760 nm, 840 nm) are radiated to living body tissue from two light sources in a probe, absorbed by both oxyhemoglobin (oxyHb) and deoxyhemoglobin (deoxyHb), and returned to the detector site in the probe.
