✦ Synopsis

i&sbauer measurements on octaethylhaemin have been made between 4.2 and 300K, and (at the lower temperature) in applied magnetic Eelds of up to 50 kG. Frcxn a spin hamiltonian treatment the saturation value of the hyperfine field at the 57Fe nucleus is found to be 495 kG, and the splitting parameter for the ferric ion levels by the axial &and field is D = 8.
