Abstract
Two crystal modifications of l-bromopentane gave entirely different Raman spectra, which undoubtedly indicated simultaneous occurrence of a crystal transformation and a conformational change of molecules in the crystal. The molecular conformation is trans-trans-trans (TTT) in one crystal modification (Crystal I) and trans-trans-gauche (TTG) in the other (Crystal II). The polymorphism of l-iodopentane, which presents a contrast to the case of 1-bromopentane, is also described.
