## time-resolved microwave conductivity (TRMC)

https://doi.org/10.1351/goldbook.T06384
Technique allowing the quantitative and qualitative detection of radiation-induced changes in the real, $$\Delta \text{Re}\sigma$$, and imaginary, $$\Delta \text{Im}\sigma$$, 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 @D01761@ or @P04711@ of molecules on excitation.
Note:
From $$\Delta \text{Re}\sigma$$ (corresponding to a change in the dielectric loss, $$\Delta \varepsilon''$$) the product of the yield and the @M03955@ of charges carriers or the @D01761@ change can be determined. From $$\Delta \text{Im}\sigma$$ (corresponding to a change in the @R05273@, $$\Delta \varepsilon'$$) the product of the yield and the change in molecular @P04711@ can be determined.
