Webv is the absorption coefficient, α a, in units of inverse length, and the thermal source function, ψ, is indeed B v which is the Planck function in watts/steradian/m2: ! B",T = … WebThe absorptivity coefficient, also known as the extinction coefficient (ε), can be established for any given protein. For each protein or peptide, the extinction coefficient can be experimentally determined or calculated from the amino acid sequence, based on the premise that the absorption of amino acids is additive. In section 2 of this note, we
