(b) Describe the principle components of a Raman microscope instrument and briefly outline its mode of operation. [10 marks) Q2 continues overleaf Page 3 of 5 (c) A pharmaceutical laboratory wishes to use a vibrational technique to perform routine qualitative analyses of a toxic material that is dissolved in water, and contained within colourless glass vials. Given these conditions, explain why Raman would be suitable for such an analysis. Your explanation should indicate why Raman spectroscopy is preferable to infrared spectroscopy in terms of the sample being aqueous, as well as the requirement that the sample should be tested without removal from the vial due to its toxicity.
