Question
need some help for fluorescence and IR, question is below
Derivatives of quinacridone are used in British banknote security threads as demonstrated in class lecture. Using the chemical structure shown below, draw the Morse potential energy diagram (Figure 1) showing a transition in the UV region and identify one chromophore in the molecule which gives this transition. Include the vibrational energy levels in the diagram but not the nodes. On another diagram (Figure 2), show no transition even though the absorption energy is correct. On another diagram (Figure 3), show how fluorescence occurs and identify a chromophore that gives this transitions and identify chromophores that gives this transition. On another diagram (Figure 4), show mid IR and near IR absorption transitions and identify chromiphores in the molecule responsible for these transitions. If you exposed the security stripe in a 50 bill to photons at 170 nm, show the Morse potential surfaces (Figure 5) illustrating the molecule dissociating. Five figures needed for this question and label all axes. Which analytical method UV-Vis, FTIR, or fluorescence would be the most sensitive method to analyze this compound that was extracted from the 50 bill and dissolved in ethanol?Explanation / Answer
we cann't give morse potential diagram here because it is obtained practicaly.
=O is cromophore here.FTIR is best
