The coupling of VV and VT energy transfer modes in molecular collisions is studied with an exponential-operator solution of the Schroedinger equation of motion. The effects of VT mode on a nominally VV process and VV mode on a nominally VT process have been calculated for the specified initial state of Vertical Bar60>. The evolution of all VV channels from Vertical Bar60> and the transformation of these channels to the final VV-VT state are discussed in detail. At collision energies of several times vibrational quantum, the VV-VT intermode coupling is so strong that energy transfer processes cannot be represented by the VV or VT mechanism alone.
