dc.descriptionWe have carried out theoretical studies of the phonons and spinons excitation spectra of $Sr_2CuO_3 $ in term of a one-dimensional model with non-adiabatic interaction magnetic and elastic subsystems using continuous time Monte Carlo method. Two gaps in triplet excitation spectrum are found. The bond defects concentration estimated is well agreement with the experimental data. The formation of magnetic moment on site at low temperature $T_N \sim 5 K$ is caused by freezing quantum spin liquid with correlation radius of antiferromagnetic ordering $ξ/a \sim 300 - 500$
