Theoretical study, and infrared and Raman spectra of copper(II) chelated complex with dibenzoylmethane

A graphene-based hybrid material with quantum bits prepared by the double Langmuir–Schaefer method

“…Peak positions found for [Cu(dbm) 2 ] were in accordance with the previous Raman, infrared and in-depth theoretical studies performed on this system and dbm ligand. 45,46 The intensity of peaks is denoted from very strong to very weak and peaks assignment is provided based on the previous theoretical and experimental study 45 (see Table S8 in the ESI †). Raman spectra conrmed unequivocally all vibrational peaks for [Cu(dbm) 2 ] to be present for both bulk as well as deposited molecules.…”

Conformation, molecular structure, and vibrational assignment of bis(2,2,6,6-tetramethylheptane-3,5-dionato)copper(II)

“…It has been shown that the calculated wavenumbers obtained at our chosen DFT level have a numerical precision that is overall satisfactory [19][20][21]. The assignments of observed wavenumbers are aided by the animation option of the GaussView 4.1.2 graphical interface [21], which gives a visual presentation of the shape of the vibrational modes.…”

“…The corresponding band in Cu(acac) 2 [20] was observed at considerably lower frequencies (448 cm -1 ), which also confirms stronger Cu-O band in Cu(tmhd) 2 than in Cu(acac) 2 . In bis(benzoylacetonato)copper(II), Cu(bzac) 2 , and bis(dibenzoylmethane) copper (II), Cu(dbm) 2 , this metal-oxygen stretching frequency is reported at 543 and 567 cm -1 , respectively [20,21].…”

Structure, luminescence and magnetic properties of an erbium(iii) β-diketonate homodinuclear complex

“…Absorption bands in the FTIR spectra have been identified in accordance with the literature. [62][63][64] The high-frequency region (3080-2850 cm À1 ) contains absorption bands originating mainly from localized CH stretching vibrations. In the spectral range from 1600 to 1250 cm À1 , the two bands centered at 1587 and 1403 cm À1 are characteristic of asymmetric and symmetric CO stretching vibrations.…”
