## Abstract Optical absorption in photonic crystals of potassium acid phthalate has been measured at room temperature, from which the band gap has been determined and the optical band gap was calculated by using absorption spectrum. The analysis of absorption coefficient in the absorption region re
## Abstract The complete single crystal Raman spectra of K~3~Mn(CN)~6~ and the Raman spectrum of an aqueous solution of this compound were recorded at room temperature. The number of lines with low wave numbers makes it possible to exclude a crystal structure composed solely of unit cells with the
