Based on the data questions B: The fluorescence quantum yield under the same conditions was determined to be 0.7. what is the intrinsic rate constant for radioactive fluorescence decay. Express the answer to two significant figures and include the appropriate unit. (Please, 0.102ns-1 is not correct) I need correct answer. QUESTIONS C: It has been determined separately that the dansyl chromophore is 20 Angstrom away from the 11 cis retinal chromophore in rhodopsin, the efficiency of fluorescence energy transfer is 50%. In a second experiment, rhodopsin is covalently labelled with a dansyl chromophore and the observed fluorescence lifetime for the dansyl-rhodopsin complex is 6 ns. What is the distance between the dansyl label and the retinal chromophore in rhodopsin. Express the answer to two significant figures and include appropriate unit. (Please, 27.7A, 21.5A are not correct answers. I need a correct answer

Part B In a fluorescence-lifetime experiment, a very short pulse of light is used to excite a sample. Then the intensity of the The fluorescence quantum yield under the same conditions was determined to be 0.7. What is the intrinsic rate constant for radiative fluorescence fluorescence is recorded as a function of time. Suppose we decay? study a dansyl fluorophore. The intensity of the fluorescent Express your answer to two significant figures and include the appropriate units. light versus time is as follows: Fluorescence intensity Time (ns) HA - 0 E ? 1.1 x 104 4.9 x 103 LO 0.10 ns 1 2.3 x 103 1.3 x 103 Submit Previous Answers Request Answer 5.6 x 102 X Incorrect; Try Again; 4 attempts remaining Part C It has been determined separately that when the dansyl chromophore is 20 A away from the 11-cis-retinal chromophore in rhodopsin, the efficiency of fluorescence energy transfer is 50%. In a second experiment, rhodopsin is covalently labeled with a dansyl chromophore and the observed fluorescence lifetime for the dansyl-rhodopsin complex is 6 ns.
