Abstract
Photoselection of elongated luminescent molecules oriented in a stretc hed polymer film is considered theoretically for the case of two- and three-photon excitation, having in mind the employment of this phenome non for determining the angle between the absorption and emission tran sition moments. Two-photon photoselection provides information on elec tronic excited states which are not detectable by conventional one-pho ton spectroscopy due to selection principles.
