Fractal analysis of photolysis of nitrosyl haemoglobin at low temperatures.
Photolysis of nitrosyl haemoglobin (HbNO) has been studied from 5.9 K to 20 K for R, T and RT conformations. It was observed that the experimental curves have two different behaviours at a given temperature in a particular conformation. At shorter time scales the data are well reproduced by a model based on fractal concepts, where the relevant parameter is the difference between the fractal dimension and the fraction. For simplicity at longer time scales a simple exponential was used to fit the curves.
