Short summary
Aerosol formation is an important process for our global climate. However, there are high uncertainties associated with the formation of new aerosol particles. We present quantum chemical calculations of large atmospheric molecular clusters composed of sulfuric acid (SA), ammonia (AM), and dimethylamine (DMA). We find that mixed SA–AM–DMA systems cluster more efficiently for freshly nucleated particles compared to pure SA–AM and SA–DMA systems.
