Population relaxation
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 … 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 …
