Short summary

With experiments performed at CLOUD, we show how isoprene interferes in monoterpene oxidation via RO₂ termination at atmospherically relevant concentrations. This interference shifts the distribution of highly oxygenated organic molecules (HOMs) away from C₂₀ class dimers towards C₁₅ class dimers, which subsequently reduces both biogenic nucleation and early growth rates. Our results may help to understand the absence of new-particle formation in isoprene-rich environments.
