The FTIR and FT Raman spectra of p-sulfonatocalix[4]arene acid, having azobenzene groups (FA), and its tetrasodium salt (S) were studied. Vibrational spectra of acid and its salts were calculated using the DFT method. The energy differences between E- and Z-forms of azobenzene groups in FA and S are...
