Ultrafast internal conversion and vibrational relaxation in singlet excited-state all-trans-β-carotene as revealed by femtosecond time-resolved stimulated Raman spectroscopy;

We have discovered that the rates of vibrational relaxation decrease with the increase of molecular dissociation energy, which phenomenon is in agreement with those from spectroscopic data.

Femtosecond time-resolved studies using fluorescence depletion spectroscopy were performed on the vibrational relaxation; orientational relaxation and the intermolecular energy transfer of dye molecules in solutions under different conditions.

Temperature effect of NMR surface relaxation in water saturated rocks;

The CBED experimental observations and computer simulations based on the dynamical theory of electron diffraction show that the surface relaxation has relatively strong influence on the displacement components in the direction perpendicular to the interface, but very weak effect on the displacement components in the plane of the interfa.

After surface relaxation,the relaxation characteristic of the first layer shows shorting in the length of Ga-N bonds.

We presented a proposal that surface relaxivity ρ is proportional to the magnetic susceptibility κ and the remanent magnetization Ir of rocks.
