WebPopulation relaxation can also occur by interactions between different centers, like energy transfers between R ions and impurities or between R ions themselves (Henderson and Imbush, 1989).This second type of energy transfer, so called cross-relaxation, can limit T 2 at high R concentration. For example, two Pr 3+ ions can exchange energy according to … WebMar 4, 2024 · State-selective population relaxation measurements. Note that in the figure m s refers to state H; m s . (a) The measurement sequence consists of preparing N-V in H; ± 1 or H; 0 , waiting time τ, and reading out the population of H; ± 1 or H; 0 . Sequences are repeated N ∼ 10 5 times.

Vibrational Population Relaxation in Liquids - Oxtoby - 1981

Human population planning is the practice of managing the growth rate of a human population. The practice, traditionally referred to as population control, had historically been implemented mainly with the goal of increasing population growth, though from the 1950s to the 1980s, concerns about overpopulation and its effects on poverty, the environment and political stability led to efforts to redu… WebSep 29, 2006 · We investigated vibrational population relaxation for the anti-symmetric stretching mode of the thiocyanate ion (SCN −) in various polar solvents by ultrafast infrared spectroscopy.In aprotic solvents, vibrational population relaxation of SCN − takes place about 2–2.5 times more slowly than in protic solvents. We found that the vibrational … tso ctso
