UV\/Vis  absorption spectrum of Cu (II)-Caffeine complex is also investigated as a function of time during refluxing to check complex formation. The molar decadic absorption coefficient of caffeine is calculated. Fluorescence emission spectra of Cu (II)- Caffeine complex is also investigated and compared with its absorption band. Area normalization analysis method is used. Finally, a better derivative fluorescence method for determination of caffeine content of substances is recommended.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838387741\"\u003e\u003ch3\u003eDeveloping Derivative  Fluorescence Techniques in Analyzing Trace Amount of  Non Fluorescing Substances\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838387741","offer_id":39469233832029,"sku":"9783838387741","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/5b32dd1b-e2ea-499d-9b15-c085ed303587.jpg?v=1757656405","url":"https:\/\/shop.autorenwelt.de\/en\/products\/photo-physical-properties-caffeine-and-cu-ii-caffeine-complex-von-tesfay-teamir","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
