One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 118-55-8, Name is Phenyl Salicylate, formurla is C13H10O3. In a document, author is Sukhodola, A. A., introducing its new discovery. HPLC of Formula: C13H10O3.
Annihilation Delayed Fluorescence of Indole and Its Derivatives in Aqueous Solution
Spectral and kinetic characteristics of annihilation delayed fluorescence (ADF) of indole and its derivatives (5-methylindole, N-methylindole) were measured in aqueous solutions at room temperature. ADF spectra of indole and 5-methylindole consisted of two bands with wavelength maxima at 350 and 425 nm for indole and 350 and 390 nm for 5-methylindole. The short-wavelength band was due to ADF of monomers and coincided with the fast fluorescence spectrum. The long-wavelength band was attributed to ADF of excimers, the excited singlet states of which were populated by annihilation of triplet excimers. Triplet states of excimers were formed by collisions of molecules in triplet and ground states. The ADF spectrum of N-methylindole consisted of only the short-wavelength ADF band of monomers (lambda = 352 nm). Lifetimes of monomer and excimer triplet states were estimated from the ADF kinetics.
