Özet: Bu çalışmada, günümüzde hesaplamalı kuantum teorilerinde önemli bir rol oynayan yöntemler olan Yoğunluk Fonksiyonel Teorisi (DFT) ve Hartree-Fock (HF) yöntemlerini kullanarak epinefrinin yapısını ve kimyasal özelliklerini tahmin etmek için bir model oluşturduk. Modelde, 6-311++G temel setinin yöntemler arasındaki fark minimum olduğu için optimal set olduğu belirlenen bant aralığı enerjilerini hesaplamak için DFT ve HF yöntemlerinin altı temel seti kullanılmıştır. 6-311++G temel seti ayrıca epinefrinin en kararlı moleküler geometrisini ve moleküler özelliklerini karakterize etmek için kullanıldı. Daha sonra, en yüksek dolu moleküler orbitalin (EHOMO) enerjisini, en düşük boş moleküler orbitalin enerjisini (ELUMO), enerji aralığını (ΔE = EHOMO - ELUMO) araştırmak için epinefrine uygulanan temel set B3LYP/6-31G(d,p) ve dipol momenti (μ). Demir yüzeyi ile epinefrin bileşiği arasındaki etkileşimi belirleyen transfer edilen elektronların oranı (ΔN) da hesaplandı. Korozyon önleyici davranış bu nedenle deneysel bir çalışma olmaksızın hesaplanan verilerden tahmin edilebilir. Hesaplamaların bulguları, organik bazlı korozyon inhibitörleri ile kuantum kimyasal parametreler süreci arasında iyi bir ilişki olduğunu göstermektedir. Bu çalışmada optimize edilen parametreleştirme ve uyarım, bilinen kimyasal formüle sahip herhangi bir bileşiğin kimyasal yapısını ve aktivitesini tahmin etmek için bir model olarak kullanılabilir.

Abstract: In this study, we built a model to predict the structure and chemical properties of epinephrine using Density Functional Theory (DFT) and Hartree-Fock (HF) methods, as the methods currently playing a significant role in in computational quantum theories. In the model, six basis sets of DFT and HF methods were used to calculate bandgap energies, which the basis set 6-311++G found to be optimal set, as the difference between the methods were minimum. The basis set 6-311++G was further used to characterize the most stable molecular geometry of epinephrine, as well as the molecular characteristics. Then, the basis set B3LYP/6-31G(d,p) applied on epinephrine to investigate the energy of the highest occupied molecular orbital (EHOMO), the energy of the lowest unoccupied molecular orbital (ELUMO), energy gap (ΔE = ELUMO - EHOMO) and the dipole moment (μ). The fraction of transferred electrons (ΔN) was also calculated, which determined the interaction between the iron surface and epinephrine compound. Corrosion inhibitor behavior can therefore be predicted from the calculated data without an experimental study. The findings of the calculations show good relation between organic-based corrosion inhibitors and quantum chemical parameters process. The parametrization and stimulation optimized in this study can be used as a model to predict the chemical structure and activity of any compound with known chemical formula.
