The effect of solute paramagnetic ions on the longitudinal magnetic relaxation rate 1/T1 of solvent water protons depends on magnetic field strength and on the chemical environment of the ions. The variation of 1/T1 with field has been measured for solutions of Gd3+ and Mn2+ ions in three grossly di

## Abstract We have developed an algorithm for sampling the conformational space of large flexible molecules in solution, which combines the molecular dynamics (MD) method and the threeβdimensional reference interaction site model (3DβRISM) theory. The solventβinduced force acting on solute atoms w
Ultraviolet upconversion emissions around 314 nm from 6 P J states of Gd 3+ ions have been observed in Y 1.98 -x Gd x Ho 0.02 O 3 (x = 0.02, 0.10, 0.20, and 0.30) oxide ceramics under the excitation of a continuous-wave 532nm laser. We found that the energy transfer process from Ho 3+ to Gd 3+ plays
