Abstract Electron paramagnetic resonance of Mn 2+ and VO 2+ in dibarium zinc formate tetrahydrate is studied at X‐band and at 298 K. The ions substitute for the Zn 2+ sites in the lattice. A correlation is found to exist between the V—O and Zn—O bond directions. The spin‐Hamiltonian parameters are evaluated. Forbidden hyperfine transitions Δ m = ± 1 and Δ m = ± 2 are observed for Mn 2+ and their doublet separations are found to be in agreement with calculated values. The angular variation of the intensities of the allowed and forbidden hyperfine transitions of Mn 2+ is also studied and is found to be in good agreement with the theory.
