Received: 19 Aug 2010 – Published in Atmos. Chem. Phys. Discuss.: 06 Oct 2010Abstract. Knudsen Effusion Mass Spectrometry (KEMS) has been used to measure for the
first time the solid state vapour pressures of a series of aliphatic cyclic
dicarboxylic acids with increasing ring size. Additionally the
atmospherically important compounds; cis-pinonic acid and levoglucosan were
also measured. Differential Scanning Calorimetry (DSC) was used to measure
melting points, enthalpies and entropies of fusion, which were used to
determine sub-cooled liquid vapour pressures for the compounds. The
sub-cooled liquid vapour pressure of straight chain, branched and cyclic
dicarboxylic acids was compared to a selection of estimation methods.
