Photothermal characteristics and light-induced structural (volume) changes of carotenoid-containing and noncontaining photosynthetic reaction centers (RCs) were investigated by wide frequency band hydrophone. We found that the presence of carotenoid

The fluorescence profile of Photosystem I/Photosystem II mixtures in different solvent systems shows that both non-hydrophobic and hydrophobic interactions govern their association and control energy transfer from Photosystem II to Photosystem I. The

The effect of copper on chlorophyll organization and function during greening of barley was examined, using chlorophyll fluorescence and photoacoustic techniques. Copper was found to inhibit pigment accumulation and to retard chlorophyll integration

Charland et al. (Biochim. Biophys. Acta 1992, 1098, 261–265) obtained photoacoustic data from sugar maple tree leaves, in which the photobaric part of the photoacoustic signal declined in time following a transition from high light to low light lev

Photoacoustic signals were measured in expanded tobacco leaves, exposed to a controlled atmosphere by being only partly enclosed within the photoacoustic cell. It was aimed to corroborate the conjecture of Reising and Schreiber (Photosynthesis Resear

A design of a photoacoustic (PA) cell for dynamic measurements in liquid samples with nanosecond time resolution is presented. The design is based on a layered scheme of laser‐induced sound excitation and detection. A theoretical basis for the use

A theoretical model of fast density changes in a solution of species undergoing photoinduced structural relaxation is presented. The model is used to explain a very fast rise time of the signal observed in a picosecond phase grating experiment on hem

A theoretical model of photoacoustic signal generation in a suspension of bacterial reaction centers (RCs) is suggested. The existing technique of separation of the two contributions to photoinduced volume changes (thermal expansion and structural re

The region between helices D and E (D-E region) of the D1 protein of photosystem II (PSII) is exposed at the stromal side of the photosynthetic membrane, contains the secondary plastoquinone (QB) binding niche, and is involved in processes at the red
