title: Study on the determination of molecular distance in organic dye mixtures using dual beam thermal lens technique.
abstract: A sensitive method based on the principle of photothermal phenomena to study the energy transfer processes in organic dye mixtures is presented. A dual beam thermal lens method can be very effectively used as an alternate technique to determine the molecular distance between donor and acceptor in fluorescein-rhodamine B mixture using optical parametric oscillator.
