Abstract

A formula is derived for the emission anisotropy r(β, Rs) of a polymer film as a function of the stretch ratio R5 of the film and of the angle β between the absorbing and emitting oscillators for the case when the long axis of the molecule makes an angle φ = 90° with the absorbing oscillator. This relation is verified, together with that obtained previously for φ = 0°. on the example of acridone and anthracene in polyvinyl alcohol. The experimental results obtained for r(β, Rs) as a function of Rs confirm the character of the predicted theoretical curves. The reasons for the lack of quantitative agreement is also discussed.
