L-Piroglutamik Asit Molekülünün TD-DFT ve NBO Analizleri

Yıl 2018, Cilt: 5 Sayı: 2, 64 - 74, 28.12.2018

Öz

Bu çalışmada, L-piroglutamik asit (L-PGA) molekülünün
konformasyonları yoğunluk fonksiyon teorisi (DFT) B3LYP/6-311++G(d,p) seti yaklaşımı
ile optimize edilmiş ve potansiyel enerji dağılımı ile bariyer enerjileri
hesaplanmıştır. L-PGA, minimum enerjiye sahip dört konformasyona sahip olup, I.
Konformasyon en kararlı yapıdadır. Molekülün II, III ve IV. konformasyonlarının
bağıl elektronik enerjileri farkı, sırasıyla 3,5, 12,6 ve 25,6 kJ mol−1
değerindedir. Konformasyonlardan en düşük enerjiye sahip molekül cis formunda,
diğer ikisi trans formunda karboksilik asit grubuna sahiptir. Fock matris
denklemleri ile donör akseptör etkileşimleri, doğal bağ orbital (NBO) analizi
ile Gaussian programına entegre NBO 3.1 programı ile incelenmiştir. Zamana-bağlı
yoğunluk fonksiyon teorisi (TD-DFT) hesaplarında, L-PGA molekülünün dalga
fonksiyonu Schrödinger kuantum mekanik denklemleri ile çözülerek, uyarılma
durum enerjileri hesaplanmıştır.
