Abstract

An influence of low intensity mm-wavelehgth radiation on spin-spin relaxation time T2 of protons in oxygen aqueous solutions was studied. Oxygen was brought in the system by the catalytic decomposition of the hydrogen peroxide. An own heterogeneity of relaxometer's magnetic field was used to observe the dynamics of medium's diffusive characteristics. The value of the slow component of the magnetization's decreasing of the induced signal was shown to depend in sharp resonance way on the external electromagnetic field's frequency under the power density P<1 mcVt/cm2- While rising up the power density to 5.0 mcVt/sm2- in the same frequency range, the increasing of spin-spin relaxation time dispersions observed.
