Photoionization study of clustering reactions in diamines: ethane-1,2-diamine, propane-1,2-diamine and propane-1,3-diamine
Abstract
Solvation of the protonated diamines species, [R(NH2)2]H+, has been studied in the systems C2H4-(NH2)2, 1,2-(NH2)2C3H6 and 1,3-(NH2)2C3H6 by high-pressure photoionization spectrometry. Clusters [R(NH2)2]nH+ up to n= 4 have been observed and the 2,3 and 3,4 equilibria of the reversible reaction [R(NH2)2]n–1H++ R(NH2)2⇌[R(NH2)2]nH+ have been examined. Thermodynamic quantities for the 2,3 and 3,4 equilibria have been determined.
