time-resolved microwave conductivity

Acronym: TRMC

Technique allowing the quantitative and qualitative detection of radiation-induced changes in the real, Δ Re σ, and imaginary, Δ Im σ, components of the conductivity of a medium by time-resolved measurement of changes in the microwave absorption resulting from the formation of mobile charges or from changes in the dipole moment or polarizability of molecules on excitation.
Note:
From Δ Re σ (corresponding to a change in the dielectric loss, Δ ε ʺ) the product of the yield and the mobility of charges carriers or the dipole moment change can be determined. From Δ Im σ (corresponding to a change in the relative permittivity, Δ ε ʹ) the product of the yield and the change in molecular polarizability can be determined.
