“…that is found consistent with doublets at 1,000, 1,025 ± 2 cm -1 observed in the resonance Raman spectra too [28,29]. The latter doublet has been assigned to proton sharing in Zundel cation located between the neighboring porphyrin macrocycles of the dimers [26].…”

“…At the same time, the tetrahedron intercalated with H 3 O + provides the possibility of deuterium creation under the X-ray absorption due to Rydberg energy (14.005934 eV) accumulation [15]. [28,29]. So that the doublet at 327, 353 cm -1 observed earlier in resonance Raman spectra of protonated TPP dimers, which matches ΔE spl = 325.51014 cm -1 , validates the fine structure of the quasiparticle composed by the electron coupled with proton in water.…”

“…In this case all excess ions are perhaps removed from the porphyrin macrocycle because of the hydrogen bonding via water molecules between two TPP units. The water coating around protonated TPP dimers in assemblies is formed due to Zundel cation operation [18,28] that provides the stronger interactions relatively those in water, while the fast proton migration through the water-porphyrin matrix produces more stable clusters. The striking effects in the absorption spectroscopy of di-protonated TPP dimers motivated the study of the detailed structural features of the assemblies up to the final crystallization.…”

“…The protonated water dimer (H 5 O 2 + ), the well-known ''Zundel cation'' exhibiting a characteristic doublet vibration near 1000 cm À1 in the infrared spectrum is generally accepted as evidence for the small-size protonated water cluster [15][16][17]. Such Zundel cations are involved in proton sharing when connecting the TPP units in their protonated clusters [18]. It has been proposed that water clusters with their tetrahedral network of hydrogen bonds influence upon the self-organization processes in aqueous solution via cooperative interactions, because the fine structure on the surface of ordered porphyrin aggregates has an intimate relation to the unique liquid water structure [18].…”
