The /,~-diketone rare earth complex: Pr(HFA)3.2HzO was synthesized and its amplitude and phase photoacoustic spectra in the range of 300-700 nm were reported. It was observed that the phase angle depends variously on the relaxation time ~ and the optical absorption coefficient ~ with the incident li
