Rayleigh light scattering properties of atmospheric molecular clusters consisting of sulfuric acid and bases.
The Rayleigh light scattering properties of (H2SO4)a(NH3)b and (H2SO4)a((CH3)2NH)b atmospheric molecular clusters have been investigated using a response theory approach. Using density functional theory the molecular structures and stepwise formation free energies of clusters with a and b up to 4 have been re-investigated. The Rayleigh scattering intensities are calculated from the dipole polar...
متن کاملMolecular understanding of atmospheric particle formation from sulfuric acid and large oxidized organic molecules.
Atmospheric aerosols formed by nucleation of vapors affect radiative forcing and therefore climate. However, the underlying mechanisms of nucleation remain unclear, particularly the involvement of organic compounds. Here, we present high-resolution mass spectra of ion clusters observed during new particle formation experiments performed at the Cosmics Leaving Outdoor Droplets chamber at the Eur...
متن کاملStructure of water–sulfuric acid clusters from molecular dynamics simulations
Molecular dynamics method is applied to study the structure of stable sulfuric acid–water clusters at various compositions. Also a planar liquid–vapor interface is studied. Two different potential models were used. In the simpler model, sulfuric acid (H 2 SO 4 ) remains in an undissociated state. A more realistic scheme requires that in the presence of water (H 2 O) H 2 SO 4 protonates to form ...
متن کاملNeutral molecular cluster formation of sulfuric acid-dimethylamine observed in real time under atmospheric conditions.
For atmospheric sulfuric acid (SA) concentrations the presence of dimethylamine (DMA) at mixing ratios of several parts per trillion by volume can explain observed boundary layer new particle formation rates. However, the concentration and molecular composition of the neutral (uncharged) clusters have not been reported so far due to the lack of suitable instrumentation. Here we report on experi...
