Spectrophotometric studies on the thermodynamic properties of charge-transfer complexes between m-DNB (1,3-dinitrobenzene) with aliphatic amines in DMSO and determination of the vertical electron affinity of m-DNB

Studies on the weak interactions and CT complex formations between chloranilic acid, 2,3-dichloro-5,6-dicyano-p-benzoquinone, tetracyanoethylene and papaverine in acetonitrile and their thermodynamic properties, theoretically, spectrophotometrically aided by FTIR

“…But whatever may be the method, K DA -values using BenesiHildebrand [37] equation under conditions D ) A or A ) D can never be regarded to be accurate values for the thermodynamic association constants though the Benesi-Hildebrand equation have been extensively used till now. The limitations of BenesiHildebrand equation were discussed in some recent publications [23][24][25][26][27]. Therefore, K DA determined in the present work can be regarded to be accurate thermodynamic K DA -values.…”

“…K DA -values determined using D % A and D ) A or A ) D (Benesi-Hildebrand method) [37] was found to differ considerably [23][24][25]. According to Foster [14], more weight should be given to K DA -values obtained from the optical density data when [D] = [A].…”

“…Interpretation of IR spectra [23][24][25][26][27] Solid charge-transfer complexes of P with acceptors stated before were isolated. FTIR spectra of the complexes and the components are presented (Figs.…”

“…The importance of CT complexes in biological systems was studied by Mulliken et al [9][10][11][12][13][14][15][16][17] Lahiri et al [18][19][20][21][22][23][24][25][26][27][28][29][30][31] made studies on CT complexes between drugs and various acceptors to explore the role of weak interactions (CT and H-bonding) in understanding drug receptor interactions.…”

Synthesis and characterization of NiFe2O4–Pd magnetically recyclable catalyst for hydrogenation reaction

“…UV-vis peak characteristic of m-DNB appears at around 240 nm [40]. It was observed that there was a very slow decrease of absorbance during the chemical reaction without catalyst (Fig.…”
