![What is a good source for broad-spectrum visible (and near IR) light? 12] 2. During a spectroscopy experiment, subjecting a sample to white light is often not a good idea. a. Why might white light irradiation be bad? [4] b. How does one avoid blasting a sample with full-spectrum light? 4] 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 34.8x10 M. It has a measured absorbance of 0.982 though a 1.00 cm cell. What is the molar absorptivity?12]](http://img.homeworklib.com/questions/cd1f8db0-fee0-11eb-a106-3996049972d8.png?x-oss-process=image/resize,w_560)
