在无碰撞条件下，质子化水团簇H+(H2O)(N)，n=5，…，65和它们的过氚类似物在放电源中产生并存储在电磁ICR离子陷阱中。由于300K黑体背景辐射的吸收，它们的碎片化或“蒸发”的速率呈现出与1/n相似的总体tau。一些团簇(如n=21或55)的局部偏离总体趋势归因于它们较高的稳定性。通过将宏观水滴蒸发外推到微观团簇来模拟破碎过程。
Protonated water clusters H+(H2O)(n), n = 5,...,65 and their perdeuterated analogues were produced in a discharge source and stored in an electromagnetic ICR-ion trap under collision-free conditions. The rates of their fragmentation or 'evaporation' due to absorption of the 300 K black body background radiation exhibit an overall tau similar to 1/n dependence. Local deviations of some clusters (e.g. n = 21 or 55) from the overall trend are attributed to their higher stabilities. The fragmentation is modeled by extrapolating macroscopic water droplet evaporation to the microscopic clusters.
