3. In a fluorescence spectrum, what quantities are plotted on the x- and y-axes? In a calibration curve for a fluorescence experiment, what quantities are plotted on the x- and y-axes? 4. Explain the difference between an excitation spectrum and an emission spectrum. Why does the excitation spectrum occur at lower wavelengths than the emission spectrum? 5. What is the main difference in the spectra resulting from atomic emission and molecular emission? 6. Describe how you would use serial dilution to prepare 100 mL of a 0.50 ppm QS solution from a 10 ppm stock QS solution.
