- •
The effect of the anisotropy of the pore space on the distribution of the spin-spin and spin-lattice relaxation times for the microcrystals, filling the pores, was investigated.
- •
It was established that the increasing in the T1 relaxation time in the wood pore-channels is observed in the case when the radio frequency field B1 is parallel to the tracheid's of wood.
- •
It was the first time that the T1ρ dispersion analysis for the paradichlorobenzene in the α-phase was made in the NQR.
