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.
