Summary

Automatic Translation

De atmosfæriske koncentrationer af svagt bundne molekylære klynger kan beregnes ud fra de termokemiske egenskaber af lavenergistrukturer, der findes gennem en multi-trins konfigurationsmetode, der anvender en genetisk algoritme og semi-empirisk og ab initio kvantekemi.
