摘要：
The wavefunction of the spatially extended excitonic state in sodium cryptand sodide is calculated in a semi-continuum approach. The magnitude of the lattice relaxation energy in a breathing mode induced by the electronic charge redistribution is computed in terms of the wavefunction. The sound speed in sodium cryptand sodide is estimated based on the fact that the lattice relaxes sufficiently to have a nonradiative deexcitation of the spatially extended state.
