As reported previously, the electron spin resonance spectrum of ferrihaemoglobin MOsaka showed a doublet signal in the g = 6 region.

The doublet signal is considered to occur as a result of a splitting of the degenerate g-value of 6.o.

When the E-term in a general spin Hamiltonian was treated as a second-order perturbation, split g-values were calculated as: gξ = 6 − 24E/D, gy = 6+24E/D and gz = 2.

The results obtained are compared with those obtained with isomeric phospholipids containing cis groupings in the 2-position of the phospholipid, and it is shown that replacement of cis by a trans double bond causes the monomolecular films to be apprechiably more condensed in character. Phase transitions are observed at different temperatures with some of the monomolecular films. The association of cholesterol with the trans phospholipids has also been measured and is found to be less favourable than with the isomeric cis phospholipids.
