AbstractPhotoselection of elongated luminescent molecules oriented in a stretched polymer film is considered theoretically for the case of two- and three-photon excitation, having in mind the employment of this phenomenon for determining the angle between the absorption and emission transition moments. Two-photon photoselection provides information on electronic excited states which are not detectable by conventional one-photon spectroscopy due to selection principles.
