Problem: In an older publication, alpha-phenylethylamine was identified using various analytical techniques, among them FTIR ("Identification of alpha-phenylethylamine in judicial samples", PMID: 8868403 Links to an external site.). In many instances, an IR spectrum obtained from a sample is compared to a database entry to confirm a match. Below shown is the spectrum of alpha-phenylethylamine and a NIST standard. Are the two samples identical? Justify your response by pointing to specific similarities and/or differences (using wavenumber ranges). What would your final conclusion be? Provide as much information as possible to show that you understand the underlying principles are making a reasoned argument.
