Vibrational SpectraImpedance method was used to measure the electrical conductivity of benzoic acid melts, and the concentration of free protons in these melts was estimated. IR spectroscopic data are presented and the existence of benzoic acid in melts in the form of molecules is suggested....
Comprehensive Forensic FT-IR Collection Library Listing – 4,286 spectra This extensive library contains materials not only of forensic interest but also for general problem solving and identification of unknown substances in industry and academia. The wide range of items include drugs, clandestine lab...
1H-NMR spectra were acquired on a Varian 400-MHz or 500-MHz spectrometer. Chemical shifts (δ, ppm) were reported against tetramethylsilane (0 ppm). MALDI-TOF MS was performed on a Voyager-DE PRO biospectrometry workstation (Applied Biosystems) using 2,5-dihydroxy benzoic acid as the ...
Complexes of M(benzoic acid)2Ni(CN)4 (M = Ni, Cd, Co and Mn) are obtained for the first time. The observed spectra indicate that the obtained complexes are new examples of Hofmann-type complexes. -PACS NO: 33.20.Ea, 33.20.Tp
energy estimation of H-complexes in benzoic acid with. D5 pyridine.(AH) intensities offer the best of the spectral measures for H-bond energies. The intensity rule, expressing the (AH) intensification-to-association enthalpy (H = O.53 1/2 direct ratio formulated by Johansen1 and most fully...
In the first experiment, para amino benzoic acid (PABA) is infrared excited using FELIX and then ionized using a vacuum ultraviolet (VUV) F2 laser. In the second experiment, C60 is multiphoton excited by FELIX to energies high enough that the molecule can undergo autoionization. In both ...
The IR spectra of p-n-cetyloxybenzoic acid, obtained in the liquid crystalline phase, are identical with the spectra obtained in the Isotropic liquid phase. The identity of the spectra indicates the formation of a large number of rotational isomer s of the n-alkyl chain of the molecules in...

spectraPhysiadsorbates and chemiadsorbates of p-hydroxybenzoic acid methylester (pHBAME) on colloidal and porous silicas were studied by IR and UV spectroscopy. In the IR spectra of self-supporting discs of the adsorbates, typical features were detected which allow differentiation between the physi- ...
