Abstract

The effect of high static magnetic field on human deoxyhemoglobin spectrophotometric characteristics is studied. Five samples of partially deoxygenated hemoglobin in aqueous solution were tested. Magnetic field was applied in steps of 2 T (tesla), from 0 to 18 T. Spectral analysis showed a higher light absorption at wavelengths of 546 nm and at 581 nm. The applied magnetic field did not alter the wavelengths at which the absorption peaks occurred. On the other hand, the light absorption was found to increase with the applied magnetic field strength up to 14 T. Copyright (C) 1998 Elsevier Science S.A.
