Web7 apr. 2024 · The Atomic spectra are defined as the Spectrum of frequencies of electromagnetic radiation emitted or absorbed during transitions of Electrons between Energy levels within an Atom. Each element has a characteristic Spectrum through which it can easily be recognized. In an Atom, Electrons have discrete and some specific energies. WebFluorescence emission spectra were recorded using 380 nm as the excitation wavelength. Measurements were performed at 20, 25, 30, 35 and 40 °C, respectively. Intensities obtained at 432 nm and 425 nm emission wavelengths were used for the binding constant evaluation of Mg 2+ -OTA 2− and Mg 2+ -OTA 2− , respectively.
