| Research Abstract |
Unraveling the complex interactions between the atmosphere and the biosphere is critical for predicting climate changes. The large amounts of biogenic volatile organic compounds (BVOCs) emitted by plants must play important roles in this regard. Here, we applied online electrospray mass spectrometry to monitor aqueous microjets exposed to gaseous terpenes and found that these BVOCs are readily protonated and undergo oligomerization upon colliding with the surface of pH < 4 microjets. Present results provide a universal mechanism for the dry deposition of unsaturated BVOCs.
