  Transition matrix elements between electronic states where one electron can
be in the continuum are required for a wide range of applications of the
molecular R-matrix method. These include photoionization, photorecombination
and photodetachment; electron-molecule scattering and photon-induced processes
in the presence of an external D.C. field, and time-dependent R-matrix
approaches to study the effect of the exposure of molecules to strong laser
fields. We present a new algorithm, implemented as a module (CDENPROP) in the
UKRmol electron-molecule scattering code suite.
