Observations of total RONO2 over the boreal forest: NO x sinks and HNO3 sources [PDF]

, 2013
In contrast with the textbook view of remote chemistry where HNO 3 formation is the primary sink of nitrogen oxides, recent theoretical analyses show that formation of RONO2 (ΣANs) from isoprene and other terpene precursors is the primary net chemical ...

Distinguishing Terpene Structural Isomers With Dielectric Barrier Discharge Ionization (DBDI)‐Mass Spectrometry

Helvetica Chimica Acta, EarlyView.
DBDI enables real‐time analysis of volatile terpenes and generates atmosphere‐dependent reagent ions that produce structure‐specific spectral patterns. By tuning humidity or dopant gases, DBDI‐MS differentiates terpene isomers that appear identical by EI.
