The model based on the effective non-hermitean Hamiltonian is implemented for studying spectrum of the vibrational metastable states of the Ne...I 2 van der Waals complex. The non-trivial behavior of the resonance positions at high vibrational excitations of the I2 fragment is explained by the intramolecular vibrational energy redistribution through intermediate resonance states. The interference effects in the resonance spectrum are elucidated by a comparative analysis of models with different choices of the active space in the Feshbach partitioning technique. It is shown that the real part of the optical potential (which is usually neglected) significantly affects positions of metastable states.
