An antianemic medication, Aronamin C Plus, which has simple iron-bearing ingredients, was studied by Mössbauer spectroscopy. The Aronamin C Plus tablet consisted of ferrous fumarate (FeC₄H₂O₄) and other ferric compounds and ferrous phases. A magnetic hyperfine field of ~ 235.7 kOe for ferrous fumarate was measured at 4.2 K. The absorption ratio of ferrous fumarate in Aronamin C Plus was estimated to be ~ 53.1% and those of the ferric and ferrous phases were found to be 22.7% and 24.2%, respectively. ⁵⁷Fe hyperfine parameters of the studied pharmaceuticals indicated the existence of major ferrous (high-spin, HS) and ferric (low-spin, LS) compounds.

穆斯堡尔光谱研究了一种抗贫血药物 Aronamin C Plus，它含有简单的含铁成分。Aronamin C Plus 片剂由富马酸亚铁 (FeC ₄ H ₂ O ₄ ) 和其他铁化合物和亚铁相组成。在 4.2 K 下测得富马酸亚铁的超精细磁场约为 235.7 kOe。Aronamin C Plus 中富马酸亚铁的吸收率估计为 53.1%，三价铁和亚铁相的吸收率为 22.7% 和 24.2 ％， 分别。所研究药物的⁵⁷ Fe 超精细参数表明存在主要的亚铁（高自旋，HS）和三价铁（低自旋，LS）化合物。
