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...
vibrational spectraFT-IR and FT-Raman spectra of benzoic acid (BA) and 3,5-dichloro salicylic acid (SA) have been recorded in the regions of 4000-400 and 4000-50 cm-1 respectively. The spectra were interpreted with the aid of normal coordinate analysis following the full structure ...

During phase transition to a smectic state of type "D," this angle must change. Figure 1 shows the IR spectra of decyloxybenzoic acid in polarized light for various phase states. An identical sign of the dichroism of individual vibrational bands was observed in the phase states of the ...
IR spectroscopic studies of the complex were performed in the middle IR region, focusing mainly on the characteristic vibrations of benzoic acid and nicotinamide, taking into account ligand functional groups within the complex. The EPR spectra of Cu(II)-doped complex were investigated at room and ...
