Abstract : The polarization of fluorescence from a polymer characterizes two segment orientation functions, fs(2) and fs(4). These may be calculated as a function of elongation using the kinetic theory of rubber elasticity. Three cases are considered: (a) the transition moment direction lies parallel to the segment axis and does not change its orientation during the lifetime of the excited state, (b) the transition moment direction lies at an angle to the segment axis, and (c) the transition moment changes its orientation during the lifetime of the excited state.
