Describe the differences in fluorescence/chemiluminscence and phosphorescence which you observed in this experiment. List one advantage...
(i) State which wavelength (primary peak) corresponds to fluorescence and also to phosphorescence? By calculating the energy of each peak, draw the energy level diagram corresponding to the graph below. Highlight transition of light absorbance, fluorescence and phosphorescence emission Briefly state with appropriate diagrams, a) why the phosphorescence emission has a longer lifetime and b) appears at a lower energy with a lower intensity. (ii) (iii) 900 800 700 600 500 400 300 200 100 350 400 450 500 550...

Questions in photo. From the Green Synthesis and Study of a Fluorescent Natural Product experiment. Fluorescence Data: Describe the observed under the UV light in the test tube and on the filter paper. (e.g. color, brightness etc. fluorescent activity of each test tube of the 4-methylumbelliferone i ) Draw the structure of 4- erone under the neutral, acidic and basic conditions. For the acidic and basic conditions drawa methylumbellif resonance structure to depict a new chromophore likely responsible for its...

Please list and briefly describe some differences between bacterial and animal cells that have not been targeted with antibiotics. For each one you list indicate whether you think this could be a target and why.
1. If you want to design an experiment to measure the fluorescence emission of ethidium bromide, what would you choose as your excitation wavelength? What would you choose as your emission wavelength? 2. Which trial has the highest concentration of ethidium bromide incorporated into DNA? Which has the lowest? Explain using the concept of fluorescence quenching. 3. Which drug occupies the most sites on DNA? Which drug occupies the least? Explain using the concept of fluorescence quenching. 4. The ethidium...
