2H and 13C NMR studies of orientational order and actual amount of n-heptane molecule in liquid crystal phases of the 7CB-n-heptane system

- The orientational order parameter of each segment of the n-heptane molecule in the liquid crystal phase in the 7CB-n-heptane system was investigated using 2H NMR.
- The actual molar fraction of the n-heptane molecule in the alky chain region of the smectic phase was obtained using 2H and 13C NMR.
- The process of formation of the swollen smectic phase of the 7CB-n-heptane system is represented.
