A comprehensive survey was made of the spectra of inorganic nitrates in the solid state pellet or mull technique. The spectra of 77 inorganic nitrates are listed in tabular form and are divided into the following four groups anhydrous ionic nitrates, anhydrous covalent nitrates, hydrated ionic nitrates, and hydrated covalent nitrates. The type of covalent bonding and methods of preparation used for the anhydrous nitrates are given. The application of the infrared data to the quantitative determination of inorganic nitrates by the pellet technique was investigated. Methods are proposed for the determination of four important inorganic nitrates sodium, potassium, barium, and strontium nitrates that are of interest to Ordnance. Methods are also proposed for the determination of two nitrates in the presence of each other. Author
