Figure 7. — Infrared spectra of the carbonyl region for (A) sterylpalmitate/oleyloleate, 1:1, m:m. Temperatures (°C) from top to bottom: 70.96, 59.47, 55.45, 52.14, 51.91, 51.37, 50.93, 50.57, 50.01, 49.41, 49.35, 48.78, 48.02, 42.74, 35.5, and 24.17. (B) Palmityloleate temperatures (°C) from top to bottom: 24.00, 20.25, 20.17, 20.14, 20.09, 20.02, 19.92, 19.85, 19.78 19.69, 19.63, 19.55 19.36, 19.16, 18.72, 18.47, 18.38, 18.35, 17.64, 16.93, 16.80, 13.59, and 12.83. (C) The carbonyl bandwidth at half height (▴) increased then decreased at the transition temperature measured by the carbonyl band center (○). All data are from heating curves. (D) Infrared spectra of the CO region: (top) sterylpalmitate/oleyloleate, 1:1, m:m, 70.96°C; sterylpalmitate/oleyloleate/cholesterylpalmitate, 2:2:1, m:m:m, 70.96°C; sterylpalmitate/oleyloleate/cholesterylpalmitate, 2:2:1, m:m:, 26.07°C; sterylpalmitate/oleyloleate, 1:1, m:m, 24.17°C; (bottom) cholesterylpalmitate 24°C.
