1. Determine whether each of the following statements is true or false. If the statement is false, modify and rewrite it so that it is a true statement. a. When a molecule has two, degenerate, "infrared active", vibrational modes, the two vibrational modes will show absorptions at different frequencies in the infrared spectrum. b. For a given substance, strong intermolecular forces between molecules of the substance can cause peak broadening of some of the absorptions in the infrared spectrum of the substance.
2. List two reasons why water is seldom used as a solvent in sample preparation for infrared spectroscopy.
