Description	Journal: Journal of Physics B: Atomic, Molecular and Optical Physics The basic integral equation of the non-local theory of inelastic resonant electron - molecule collisions is recast in the form of a system of differential equations for a set of the electron resonance pseudostates. These pseudostates are related to the quadrature approximation for the spectral integral over the interval of the electron continuum with some set of N complex-valued resonance energies and residues . The system of differential equations is solved with the split propagation method for treatment of initial wavepacket time evolution. This approach is not restricted (in principle) by the dimensionality of the configurational space and by the form or representation of the basic characterisitics of the system. The method is applied for calculation of the inelastic cross sections for - HCl and DCl collisions. The results obtained are in excellent agreement with the previous calculations. In contrast with previous investigations of the problem, the present approach allows one to consider the process as Markovian. This feature is very important for the assessment of non-local theory applicability for the investigation of inelastic electron - polyatomic-molecule collisions.
