“…It is considered that there are different conditions between experimental results and theoretical calculations. 129 The value of l max in the first excited state of the NH 2 -Cdots decreases (blue shift) after interacting with H 2 O 2 . The probability of absorption or emission of electromagnetic radiation in the transition between energy levels is represented by the oscillator strength ( f ).…”

Synthesis and Activity Test of Coumarin-Chalcone Derivative as a Colorimetric Sensor for Chicken Spoilage Indicator

“…One of the previous strategies adopted for the design of amine sensors is based on the use of coumarin-chalcone derivatives, which interact with anion through hydrogen bonding. In this paper we would like to report that compound of 3-(3-(3-Methoxy-4-hydroxybenzene)-prop-2-enoyl)-2H-2-chromenone (2), a coumarin-chalcone derivative, is a promising candidate for colorimetric chemosensor for amines because it has hydroxyl chalcone group as a binding site to form delocalization electron [9].…”

Density-Functional-Theory Calculations of Formation Energy of the Nitrogen-Doped Diamond

“…To model a defective system, a theoretical approach based on the density functional theory (DFT) is frequently conducted since DFT can successfully reproduce the experimental results [10][11][12][13]. In the previous theoretical studies, it was shown that borondoped diamond produces the blue-colored diamond, and nitrogen-doped diamond yields to the yellow one [1].…”
