A donor-acceptor nanocluster under an IR radiation field (λ = 16–18 nm) is reported. The donor molecule in the nanocluster contains a polar C$_n$H$_{2n}$ substructure that serves an IR antenna for this radiation. The accepter is a dimer of nonpolar pyrene molecules. The induced dipole moments of the pyrene molecules that arise in the field of the IR antenna dipole moment is studied. It is assumed that the induced dipole moment of each pyrene molecule in the dimer produces an extra electrostatic field that affects the neighboring pyrene molecule in the dimer. The analytical expressions for this process are obtained and the relevant analysis of the dynamic phenomena is performed. It is established that the value of the induced molecular dipole moment in pyrene dimer is much larger than the same value in the pyrene monomer. This leads to the increasing probability of the induction processes in nanoclusters in comparison with the same processes in nanoclusters with a single pyrene molecule in accepters.
