Twenty one conformationally fixed amines and their N,N-dimethyl derivatives were obtained commercially or synthesized. These included cis and trans 4-t-butyl cyclohexylamine, 2-exo and 2-endo norbornylamine, 2-adamantylamine, 4-phenylpiperidine, 1-napthylamine and tetrahydro-1-napthylamine. The (1)H NMR spectra of these amines were measured in CDCl(3) solution, assigned and the (1)H chemical sh...

The effect of cypermethrin pesticide on juvenile rohu (Labeo rohita) was determined in captive condition. Live and healthy (average initial weight 21g) were exposed to five concentrations Cypermethrin 0.63, 0.13, 0.025, 0.005, 0.001 ppm one control group (no pesticide) with two replications for each treatment. mean temperature pH the experimental tanks 27.53±0.41ºC 7.22±0.013 ppt, respectively....

The thermodynamic functions such as enthalpy (H), Gibbs free energy (G) and entropy (S) of Serineand Threonine amino acids were theoretically studied at different condition (solvents andtemperatures) by using Gussian o3, software. First, the structural optimization of isolated Serine andThreonine were done in the gas phase by using the Hartree-Fock (HF) level of theory with 3-21G, 6-31G and 6-3...

Bu çalışmada kristal yapıları önceki çalışmalarda belirlenmiş olan diaquabis(4-florobenzoat)bis(nikotinamid) kobalt (II) ve diaquabis(4-bromobenzoat)bis(nikotinamid) komplekslerinin moleküller arası etkileşimleri Hirshfeld Yüzey Analizi ile belirlenmiştir. Moleküllerarası etkileşim katkı yüzdeleri iki boyutlu parmak izi grafiklerinden elde edilmiştir. Komplekslerin enerjileri CrystalExplorer pr...

hydrogen bonding of dppe with water that surrounded of membrane, plays an important role in permeability ofmembrane that we were presented this matter with analysis of bond angles and torsion angles before and after ofadded water molecules.interaction with water molecules causes some changes in the geometry of dppe which were explained bythe contribution of zwitterionic form of dppe molecule, a...
