Technique allowing the quantitative and qualitative detection of radiation-induced
changes in the real,
, and imaginary,
,
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
(corresponding to a change in the dielectric loss,
)
the product of the yield and the
mobility of charges carriers or the
dipole
moment change can be determined. From
(corresponding to a change in the
relative permittivity,
)
the product of the yield and the change in molecular
polarizability can be determined.
