We propose to establish a numerical method to calculate the Siegert states of molecular solution of the stationary Schrödinger equation satisfying the regularity and outgoing-wave Siegert boundary conditions. This work follows the previous one on the atomic Siegert states in an electric field. The previous method enabled the calculation of complex energy eigenvalues and eigenfunctions for one-electron atomic potential. Here we extend the method to molecular cases. We describe necessary modifications for obtaining complex energy eigenvalues and eigenfunctions in more complex molecular cases. We give preliminary results obtained for the simplest molecular ion, \({\mathrm{H}}_{2}^{+}\).
