metformin hydrochloride (mfh) is an oral anti-diabetic drug of biguanide class. two selective spectrophotometric methods were presented for the determination of mfh in pharmaceuticals. the methods were based on the measurement of yellow-coloured charge-transfer complexes formed between mfh and two poly-nitrophenols, namely, 2,4-dinitrophenol (dnp method, at 405 nm) and picric acid (pa method; a...
We present a theoretical study of the positive charge transfer in stilbene-linked DNA hairpins containing only AT base pairs using a tight-binding model that includes a description of structural fluctuations. The parameters are the charge transfer integral between neighboring units and the site energies. Fluctuations in these parameters were studied by a combination of molecular dynamics simula...
The role of charge transfer in halogen bonding is the subject of an ongoing debate and controversy. It is clear from experimental data that charge transfer occurs in halogen bonds, but its contribution to the energetics of the interaction can be evaluated only computationally. Since the charge transfer is not a physically well-defined property, there are multiple computational approaches, which...
