Abstract
The infrared spectra of solid films of piperidinium halides were measured at both room temperature and low temperatures. The spectra of the chloride and the bromide are not appreciably affected by cooling, but the spectrum of the iodide exhibits spectacular changes. These changes are explained by assuming the occurrence of a phase transition at about −15 °C. The possibility of a "chair" → "boat" interconversion is also discussed.Keywords
