35Cl Nqr

AbstractThe crystal structure of cyclohexylhemiacetal (cycHx-CH) was determined at 296 K : monoclinic, space group P21/c, a =1028.7 (9), b = 609.5 (1), c = 1811.9 (4) pm, and ß = 99.79 (3)°, Z = 4, R = 0.0552. The three 35Cl NQR lines in cycHx-CH, T1, T2, and T2*, were measured by a pulsed method at 80-300 K. Below 200 K T1-1 obeyed the T law well, indicating that the spin lattice relaxation is governed by lattice vibrations. The reorientation of CCl3 seems to be responsible for the sharp T: drop observed above 250 K. Shoulders in the T1 vs. 1/T curves indicate the presence of T1 minima at about 240 K. A fluctuation of the EFG due to a dynamic disorder of hydrogen atoms in the OH groups is assumed to explain the T1 minima.

Layered Crystal Structure

The frequencies of the long-wavelength lattice vibrations of SnS crystal with a layered crystal structure have been calculated in the linear chain framework. It has been shown that these frequencies fall as the size of the crystal across layers decreases. A significant softening of the low-frequency Raman-active modes has been established as the thickness of a crystal is reduced to two layers.
