Energy Component Analysis for Electronically Excited States of Molecules: Why the Lowest Excited State Is Not Always the HOMO/LUMO Transition

open access: yesJournal of Chemical Theory and Computation, 2023
The ability to tune excited-state energies is crucial to many areas of molecular design. In many cases, this is done based on the energies of the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO).

Structure reactivity analysis for Phenylalanine and Tyrosine

open access: yesCumhuriyet Science Journal, 2021
Phenylalanine (Phe) is one of the amino acids that cannot be produced in the body and must be ingested through diet. Tyrosine (Tyr) is also a non-essential amino acid and can be produced by Phe hydroxylation in the liver when the dietary intake of Tyr is
