Summary

Traduzione automatica

De atmosferische concentraties van zwak gebonden moleculaire clusters kunnen worden berekend op basis van de thermochemische eigenschappen van lage energiestructuren gevonden door middel van een multi-step configuratie bemonstering methodologie met behulp van een genetisch algoritme en semi-empirische en ab initio kwantumchemie.
