Electronic excitation energy quenching of an organic liquid scintillator by carbon tetrachloride in different solvents

Analysis of fluorescence quenching of new indole derivative by aniline using Stern–Volmer plots

“…the radius of sphere of action) the static effect takes place especially in the case of steady-state experiments irrespective of ground state complex formations provided the reactions are limited by diffusion. From Table 1, it is observed that the values of kinetic distance r (r 0 ) are higher than the encounter distance R in all the solvents indicating the sphere of action static quenching model agrees well in our case also [10][11][12][13][14].…”

“…In many cases, the S-V plots were found to be linear, in which the quenching mechanism is mainly due to the dynamic process, where diffusion process is the dominant one [10,11]. In some cases, the experimental results show positive deviation from the linear S-V relation [1][2][3][12][13][14].…”

Quenching mechanisms of 5BAMC by aniline in different solvents using Stern–Volmer plots

“…From Table 3, we see that k q approximately equal to 4pN 0 R 0 D and k a 4k q or alternatively k a 4k d , may suggest that quenching is less efficient in benzene, dioxane, tetrahydrofuran and dimethylformamide than in the remaining solvent [16,28]. This may be due to the fact that the activation process is more predominant in the quenching mechanism than the diffusion process.…”

“…The study has been mainly to understand the nature of bimolecular reactions taking place both under steadystate and transient conditions. This study has not only been of importance in physical sciences but also in chemical, biological and medical sciences [7][8][9][10][11][12][13][14][15][16][17][18][19]. The fluorescence yield in bimolecular liquid systems is hindered due to several mechanisms such as static and dynamic quenching, excimer and exciplex formation, charge transfer processes, etc.…”
