- Descrição
- Spin lattice relaxation of <math>Fe^{3+}\,\!</math> has been measured as a function of temperature in azide methemoglobin in natural and heat denaturated condition. Of the two spin states present (S=1/2, and S=5/2) the high spin state always follows an Orbach mechanism of relaxation with a characteristic energy dependent on the protein conformation. In the absence of thermal equilibrium of the two spin states, the S=1/2 state follows a Raman relaxation process whose exponent, n, is related to the conformation of the protein.
