Categories Ask Chemistry Absorption and Emission at same wavelength? Post author By Q+A Expert Post date October 18, 2020 No Comments on Absorption and Emission at same wavelength? Is it possible for a molecule to absorb and emit at the same wavelength? What is the reason behind it? I’m working on charged Tin porphyrins and got the excitation and emission (fluorescence) wavelength around 400nm. For clarification, I have attached the exciation and emission profile for the tin system. Can somebody help what would be the reason? ← How to vertically centre elements in a div? → Resistance dependent pricing for resistors Leave a Reply Cancel replyYour email address will not be published.
