Abstract
AbstractThe temperature‐dependent vibrational infrared and Raman spectra of 20% solutions of decylammonium chloride in H2O (D2O) were studied. According to previous work, phases SI and SII were identified in the low‐temperature range. Molecular and supermolecular structures were derived. The upper shift (Δν = 12 cm−1) of the Raman‐active antisymmetric stretching CH2 mode (d−) and its narrowness are peculiar and specific signals of a specific structure. It is proposed that the phase transition SI → SII is originated by the onset of a conformational flexibility generally described as twistons or conformational solitons. No evidence was found that the alkyl residues have librational freedom about their axes.
