What is it about?
We theoretically explore why a recent experimental observation was made in the singlet fission process. Singlet fission is a process in organic materials wherein an excited electron-hole pair (exciton) splits into two lower energy excitons. Recently, a surprising observation was made wherein the spin quantum number was not conserved. This paper provides a theoretical framework for understanding this observation.

Why is it important?
Singlet fission has use in solar cells and if fully exploited can increase the efficiency of existing technologies by 50%. We need to understand all of the loss channels if we are to achieve this - this paper is a step in this direction.
