Turgay Polat

TL;DR: The varying magnitude of nickel determined in the aboveground parts of the test plants indicated that the resistance or vulnerability and Ni requirements of a plant species were species-specific and were more effective than the Ni amount in the soil on the uptake of the element.

TL;DR: In this article, the theoretical and experimental studies were carried out on 7-fluoroisatin, 7-bromoisatin and 1-methylisatin using FT-Raman and FT-IR spectra.

TL;DR: The correlations between the experimental and theoretical findings for the molecular structures improve with the enhancement of the solvent polarity, and it is found that the CO and NH stretching vibrations shift regularly to lower frequency value with higher IR intensity as the dielectric medium enhances systematically due to the intermolecular NH⋯O hydrogen bonds.

TL;DR: In this article, the authors used the B3LYP/6-311++G ∗∗ DFT method to find the predominant tautomer among seven possible isomers of 2-hydroxyquinoxaline 2-OHQ.

TL;DR: Optimize geometric parameters, conformational equilibria, normal mode frequencies, and corresponding vibrational assignments of 3M3HI4C were theoretically examined by quantum chemical methods for the first time and the most stable conformer of the title compound was determined.
