  Using finite temperature Lanczos technique on finite clusters we calculate
dynamical spin structure factor of the quasi-two-dimensional dimer spin liquid
SrCu2(BO3)2 as a function of wavevector and temperature. Unusual temperature
dependence of calculated spectra is in agreement with inelastic neutron
scattering measurements. Normalized peak intensities of the single-triplet peak
are q-independent, their unusual temperature dependence is analyzed in terms of
thermodynamic quantities.
