Abstract
Bu çalışmada, N-Schiff bazı grubu içeren bileşiklerin moleküler yapısının literatürden alınan deneysel verileri, teorik yöntemlerle elde edilen verilerle karşılaştırılmıştır. İncelenen, L1 ve L2 N-Schiff bazlarının deneysel verilerinin doğruluğunu desteklemek için Gaussian 09 ve GaussView 5 paket programları kullanılmıştır. Teorik hesaplamalar için Gaussian 09 ve GaussView 5 paket programları, baz seti olarak 6-31G(d,p) seçilmiştir. Yoğunluk Fonksiyoneli Teorisi (Density Functional Theory, DFT) yöntemi ile N-Schiff bazlarının moleküler geometrisi, IR ve NMR spektrumları teorik olarak belirlenmiştir. Moleküllerin enerjileri, moleküler elektrostatik potansiyelleri ve HOMO ve LUMO orbitalleri hesaplama yoluyla ayrıca elde edilmiştir. N-Schiff bazlarının deneysel IR ve NMR değerleri hesaplanan değerlerle uyum içinde olduğu gözlemlenmiştir.
In this study, empirical data obtained from the literature for the molecular structure of compounds containing a group of Schiff bases were compared with data obtained using theoretical theoretical methods. Gaussian 09 and GaussView 5 were used to support the accuracy of the empirical data for the L1 and N-Schiff bases. A basis set of 6-31G(d,p) was selected for the theoretical calculatations in Gaussian 09 and GaussView 5. The molecular geometry, IR, and NMR spectrums of the N-Schiff bases were theoretically determined using Density Functional Theory (DFT). Molecules' energy, their electrostatic potentials, and both their HOMO and LUMO orbitals were calculated. N-Schiff bases' empirical IR and NMR values were observed to be compatible with the calculated values.
