The colour transitions between the forms of myoglobin simulation

Murashev S.V., Vorobyov S.A.

A substance colour formation is a process of selective absorption of a part of the visible light from the white light falling on its surface. Absorption of a part of the visible light by the pigments occurs in the electronic transitions. In the haem group of myoglobin, the basic muscular tissue pigment, 2 types of such transitions are possible: resonance absorption of the luminous energy in the porphyrin ring π - electronic system and the d-electronic ion transitions of the complex former metal. Visible light combination, which has not been absorbed in the electronic transitions, generates pigments’ colour. To simulate the colour transitions between the forms of myoglobin it is necessary to summarize in a certain sequence the visible light not absorbed by the pigments.
