WebWe paid special attention to their magnetic parameters and the conditions of their stabilization during the photolytic cleavage of arylphosphiranes. An unusual influence of o -substituents on the spin–orbit component of the ZFS parameters D is observed. WebThis is called homolytic cleavage or homolysis. The electron pair separates evenly to each part, and as a result both products contain a single electron. The species that contains one or more single electron is called a radical (or free radical). Radicals are produced from homolytic cleavage.
