Recently measured high-field ESR spectra of the spin dimer material ${\mathrm{TlCuCl}}_{3}$ are described within the framework of an effective field theory. A good agreement between the theory and experiment is achieved, for all geometries and in a wide field range, under the assumption of a weak anisotropy of the interdimer as well as intradimer exchange interaction.
