1. The problem statement, all variables and given/known data The question relates to carbonic anhydrase with Zinc at the biosite. (1ca2 on protein data bank). Q: Why can you not study the water bound to the zinc when the molecule is in an aqueous solution? 2. Relevant equations n/a 3. The attempt at a solution I've had a few thoughts but im getting myself confused... My course materials tell me that water is transparent to the wavelength of radiation being used (UV-Vis), but that was simply in relation to raman spectroscopy. Is this still the case of resonance raman spectroscopy?
