RBCO (R = Y and Rare Earths) powders have been prepared via solid state reactions. From these powders large single-crystal (particularly of Nd, Sm and Eu) 123 phase have been grown by the flux method. FT-IR and FT-FIR infrared transmission analysis of powders and infrared reflection of single crystals have been investigated. An interpretation of the vibrational structure of the orthorombic 123 phase is proposed.

Abstract
RBCO (R = Y and Rare Earths) powders have been prepared via solid state reactions. From these powders large single-crystal (particularly of Nd, Sm and Eu) 123 phase have been grown by the flux method. FT-IR and FT-FIR infrared transmission analysis of powders and infrared reflection of single crystals have been investigated. An interpretation of the vibrational structure of the orthorombic 123 phase is proposed.
