Procedure and results of computation of optical and infrared spectra of ultracool (1000 < Teff < 3000 K) objects are discussed. LTE synthetic spectra and spectral energy distributions in wide spectral region λλ 0.6–10 microns) are computed for model atmospheres from grids of different authors taking into account opacities provided by water and other molecules.

Essential interest will be paid for problems of realization of lithium and deuterium tests which can be used for assessment of objects of sub-stellar masses and big planets and refining of scenarios of evolution of young stars and substellar objects.
