Abstract Azurite [Cu 2+ 3 (CO ) 2 (OH) ] and malachite )(OH) are both monoclinic hydroxy carbonates of copper. The Raman spectra these two minerals were collected at 298 77 K together with the single crystal azurite K. contain modes three separate vibrational groups: OH, CO Cu O. Accordingly, for bands 3453 3427 cm −1 have been assigned as O H stretching mode bending found 1035 952 . Malachite displays hydroxyl 3474 3404 which shift to 3470 3400 while out‐of‐plane 1045 875 For carbonate...
Radical assembly: Halogen bonding has been observed for the first time between an isoindoline nitroxide and iodoperfluorocarbon (see figure), which cocrystallize to form a discrete 2:1 supramolecular compound in N--O(.)I halogen is dominant intermolecular interaction. This illustrates potential use of tectons assembly organic spin systems.The 1,1,3,3-tetramethylisoindolin-2-yloxyl (TMIO) 1,4-diiodotetrafluorobenzene readily complex that shows evidence relatively strong bonding. interaction...
Polyacrylamide gels (PAGs) are used for magnetic resonance imaging radiation dosimetry. Fourier transform (FT) Raman spectroscopy studies were undertaken to investigate cross-linking changes during the copolymerization of polyacrylamide in spectral range 200-3500 . Vibrational bands 1285 and 1256 assigned acrylamide bis-acrylamide single binding modes. Bands found decrease amplitude with increasing absorbed dose as a result copolymerization. Principal component regression was performed on...
Polarisation Raman microscopy is used to study tubular chrysotile. The OH-stretching region characterised by the inner surface OH bands at 3695, 3686 and 3678 cm-1 band 3643 cm-1. outer pointing away from Mg-layer gives rise two overlapping 3695 due a positional disorder caused folding of layers. These are in-phase vibrations whereas represent out-of-phase vibrations. 1102 an antisymmetric stretching mode Si–O perpendicular sheet. From 692 705 first one assigned symmetric Si–O–Si stretch...
The effects of ionizing radiation in different compositions polymer gel dosimeters are investigated using FT-Raman spectroscopy and NMR T2 relaxation times. manufactured from concentrations comonomers (acrylamide N,N'-methylene-bis-acrylamide) dispersed an aqueous gelatin matrix. Results analysed a model fast exchange magnetization between three proton pools. fraction protons each pool is determined the known chemical composition dosimeter spectroscopy. Based on these results, physical...
