The theory presented in this article series - and in my PhD thesis - lay the foundations for the study of the radical pair-based theory of avian magnetoreception, i.e. the theory that a pair of transient radical pairs are responsible for the magnetic compass sense used by migratory song birds. Additionally, the theory may also be applied to the study of possible effects of radio waves (oscillating magnetic field in particular) on biological cells.
A few modifications were made to the text before it was brought online here as an article series, in order to conform with the format of this website. The most important change was stripping the text of all citations, and instead some relevant textbook references were added in the sidebar.
Note that the MolSpin software was developed to perform many of the calculations that are described in this article series.
