Summary[edit]
| Description |
English: Chemiluminescence
- A solution of oxalyl chloride is prepared in dichlorometane, and some rodamine is added to it. Aqueous H2O2 is added to it (the mass ratio is between 0,1 and 0,15). An instantaneous chemiluminiscence is noticed, as a consequence of formation of a peroxide product in an excited state. The subsequent deexcitation is followed by emition of UV radiation that is registered by the molecules of colour present (those emitting in the visable region). Planned and performed by Marina Stojanovska, Miha Bukleski and Vladimir Petruševski, Department of Chemistry, FNSM, Ss. Cyril and Methodius University, Skopje, Macedonia.Македонски: Хемилуминисценција
- Во раствор од оксалил хлорид (COCl)2 во дихлорометан се раствора и малку родамин. Кон системот се додава воден раствор од водород пероксид (со масен удел околу 0,1–0,15). Моментно започнува интензивна хемилуминисценција. Ова е последица на образување ексцитирани молекули од продуктот на оксидација (своевиден пероксид) и нивна последователна деексцитација во вид на UV зрачење. Ова зрачење е она што ги побудува молекулите на бојата да емитираат видлива светлина. Осмислено и изведено од Марина Стојановска, Миха Буклески и Владимир Петрушевски, Институт за хемија, ПМФ, УКИМ, Скопје. |
