Notes:
The polarized infrared spectra of crab chitin crystallites, blowfly larval cuticle, lobster tendon, and partially deacetylated lobster chitin have been studied. In addition, the spectra of amorphous deacetylated chitin, deuterated lobster chitin and crystalline N-acetylated chitohexaose were obtained and analyzed. Band assignments have been made with the aid of previous work on celluloses and other related molecules. The complete intermolecular C=O----H—N hydrogen bonding scheme, orginally proposed by Carlstrom from x-ray studies, is in agreement with the infrared data. With the aid of a scale model of the chitin unit cell, a number of hydrogen-bonding schemes involving the primary hydroxyl group have been examined and are discussed.
