Dication chemistry
WebAcetylene is a simple molecule of interest for interstellar medium (ISM) and planetary atmospheres. The presence of C2H2 was detected by IR spectroscopic measurements. Acetylene was also found as a minor component in the atmosphere of gas giants like the planet Jupiter, in the atmosphere of Saturn’s satellite Titan, and in comets, where … WebIn wet-chemistry, ABTS 2+ forms with an excess of the oxidant under strongly acidic conditions [42,43]. Among the abiotic oxidants of ABTS, MnO 4 −, Cr 2 O 7 2−, and Cr(IV) generated the red dication.Its rapid decay was delayed by S 2 O 8 2− for more than three days [44]. Among inorganic peroxides generating the ABTS •+ cation radical, …
