The photoacoustic spectrum of Anacystis nidulans recorded at room temperature is qualitatively similar to low-temperature absorption or fluorescence excitation spectra. The bands of pigment holochroms are well resolved compared to room-temperature absorption spectra. The thermal deactivation spectrum obtained by extrapolating acoustic data for an infinitely thin sample indicates that the photosynthetic efficiency decreases from phycocyanin to chlorophyll a and carotenoids.
