Q1
Counterfeit drugs are a common problem in developing regions of the world. Oftentimes, counterfeit pills are made with compounds such as lactose. A lab technician has obtained the IR spectrum shown above for a sample reported to be citalopram, an antidepressant drug. Does the IR spectrum belong to citalopram or lactose? Explain your answer by describing what feature of the IR spectrum confirms your choice and describe what feature is missing from the IR spectrum for the other compound. A. citalopram B. lactose
