Question

Please throughly complete these problems 2ab,3ab and 4! I need help with these! Thank you 2. During a spectroscopy experiment, subjecting a sample to white light is often not a good idea. white light irradiation be bad? I4] b. How does one avoid blasting a sample with fullspectrum light? 3. oxygen will react in something called the "Chapman Cycle" when exposed to short-wave UV light. A lamp that produces broad-spectrum UV light will drive this reaction. a. Write the reaction and identity the product. [5] b. That product is not something you want to breathe! How could you avoid its formation? [4] 4. An organometallic compound is made up to 34.8x105 M. It has a measured absorbance of 0.982 though a 1.00 cm cell. What is the molar absorptivity?121

Explanation / Answer

White light consist of seven different lights which have different energy. If you irradiate a molecule with white light, it can absorb all of these seven lights and all the different changes will occur together. In spectroscopic measurement we observe a perticular change. For example, either in romational energy level, or in electronic energy level etc. But if all the changes occur together, it will be difficult to monitor. So, you have to use a perticular wavelength rage for which you want to see the change.

Use a monochromator/ use a radiation source which emitts light of one range
