Title:Temperature-dependent Water Uptake Behavior Of Clusters Relevant To New Particle Formation

Subject(s):Atmospheric science
Abstract:New particle formation is a process in which trace vapors in the atmosphere cluster and grow into larger particles. Recently, we have employed a multi-trap gas-phase ion preparation technique and cryogenic ion vibrational predissociation (CIVP) spectroscopy to identify common structural motifs for the uptake of water into cationic clusters relevant to NPF. Here we further extend this exploration using a multi-trap gas phase variable temperature mass spectrometry (VTMS) technique in which we probe the water uptake of clusters as a function of temperature to determine the associated thermodynamic parameters. We then seek to correlate these water uptake parameters to structural motifs present in the dry clusters.
