Abstract
WHEN the first attempt was made to determine the coefficient of accommodation of free organic radicals, a ‘guard mirror’ of lead was placed in front of a second mirror; by gradually reducing the length of the guard mirror until the second mirror was attacked, it was possible to show with a fair degree of accuracy that free radicals reacted with a lead mirror at every first impact. On a clean glass wall no more than about one in a thousand radicals was not reflected1.
