The fine structure of the spectra of a shallow-level Li donor center and a Fe{sup 0} deep donor (S = 1), which occupy tetrahedral interstices in a silicon lattice, is studied in monoisotopic silicon {sup 28}Si due to considerable narrowing of the lines of ESR spectra. In the case of the Li donor center, experimental data are found to confirm the role of internal strains in the crystal when observing the ESR spectra of the ground state 1s T{sub 2} and state E at T = 3.8-10 K with g < 2.000. The anisotropy in the distribution of strains, which turned out to have a tetragonal type, is investigated using the angular dependences of the line width of the spin resonance corresponding to the triplet state T{sub 2z} of Li. Similar anisotropy is found in the case of the introduction of Fe{sup 0} ions into the initial crystals based on the theory of angular dependences of the width of ESR lines caused by the transitions -1 {yields} 0 and 0 {yields} +1 ({Delta}M{sub s} = 1) in comparison with the transition -1 {yields} +1 ({Delta}M{sub s} = 2).
