The paramagnetic resonance of Mn++ in various lead salts has been observed at 1.3 and 77°K. The spectrum shows hyperfine splitting, but no crystal-field splitting. The hyperfine constant of Mn++ in PbS, PbSe, and PbTe is 71.8, 67.6, and 61.2×10-4 cm-1, respectively. An anomalous g shift of the hyperfine lines is attributed to the electronic equivalent of the Knight shift. Electronic inhomogeneity in PbSe results in two separate sets of hyperfine lines. It is suggested that the inhomogeneity is due a clustering of lead vacancies. The spectrum of Eu++ in PbSe is also reported.
