Substituent effect on IR, 1H- and 13C-NMR spectral data in N-substituted phenyl)-2-cyanoacetamides: A correlation study / Uticaj supstituenata na IR, 1H- i 13C-NMR spektralne podatke N-(supstituisanih fenil)-2-cijanoacetamida - korelaciona analiza
(Association of the Chemical Engineers of Serbia, 2013)
Linear free energy relationships (LFER) were applied to the IR, 1H- and 13C- -NMR spectral data of N-(substituted phenyl)-2-cyanoacetamides. A variety of substituents were employed for phenyl substitution and fairly good ...
The effects of solvents and structure on the electronic absorption spectra of the isomeric pyridine carboxylic acid N-oxides / Uticaj rastvarača i strukture na elektronske absorpcione spektre izomernih piridin-karboksilnih kiselina N-oksida
(Association of the Chemical Engineers of Serbia, 2013)
The ultraviolet absorption spectra of the carboxyl group of three isomeric pyridine carboxylic acids N-oxides (picolinic acid N-oxide, nicotinic acid N-oxide and isonicotinic acid N-oxide) were determined in fourteen ...
Lipophilicity assessment of some 5,5-disubstituted hydantoins by the means of reversed phase liquid chromatography / Procena lipofilnosti nekih 5,5-disupstituisanih hidantoina primenom tečne hromatografije na obrnutim fazama
(Association of the Chemical Engineers of Serbia, 2013)
The retention of some 5,5-disubstituted hydantoins was investigated by reversed phase high performance thin-layer chromatography (RP HPTLC) and reversed phase high-pressure liquid chromatography (RP HPLC). The mobile phases ...
