  • Atmospheric chemistry of diazomethane – an experimental and theoretical study 
    Antonsen, Simen Gjelseth; Bunkan, Arne Joakim Coldevin; Mikoviny, Tomas; Nielsen, Claus Jørgen; Stenstrøm, Yngve H.; Wisthaler, Armin; Zardin, Erika (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    The kinetics of the O3, OH and NO3 radical reactions with diazomethane were studied in smog chamber experiments employing long-path FTIR and PTR-ToF-MS detection. The rate coefficients were determined to be k CH2NN+O3 =  ...
  • Atmospheric Chemistry of Methyl Isocyanide – an Experimental and Theoretical Study 
    Antonsen, Simen Gjelseth; Bunkan, Arne Joakim Coldevin; Mikoviny, Tomas; Nielsen, Claus Jørgen; Stenstrøm, Yngve H.; Wisthaler, Armin; Zardin, Erika (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    The reaction of CH3NC with OH radicals was studied in smog chamber experiments employing PTR-ToF-MS and long-path FTIR detection. The rate coefficient was determined to be kCH3NC+OH = (7.9 ± 0.6) × 10–11 cm3 molecule–1 s–1 ...
  • Atmospheric Chemistry of N-Methylmethanimine (CH3N=CH2): A Theoretical and Experimental Study 
    Bunkan, Arne Joakim Coldevin; Reijrink, Nina G.; Mikoviny, Tomas; Müller, Markus; Nielsen, Claus Jørgen; Zhu, Liang; Wisthaler, Armin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    The OH-initiated photo-oxidation of N-methylmethanimine, CH3N═CH2, was investigated in the 200 m3 EUPHORE atmospheric simulation chamber and in a 240 L stainless steel photochemical reactor employing time-resolved online ...
  • Atmospheric Chemistry of tert-butylamine and AMP 
    Antonsen, Simen Gjelseth; Bunkan, Arne Joakim Coldevin; D'Anna, Barbara; Eichler, Philipp; Farren, Naomi J.; Hallquist, Mattias; Hamilton, Jacquiline F.; Kvarnliden, Hampus; Mikoviny, Tomas; Müller, Markus; Nielsen, Claus Jørgen; Stenstrøm, Yngve H.; Tan, Wen; Wisthaler, Armin; Zhu, Liang (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The atmospheric chemistry of (CH3)3CNH2 (tert-butylamine, tBA) and (CH3)2(CH2OH)CNH2 (2-amino-2-methyl-1-propanol, AMP) has been studied by quantum chemistry methods and in photo-oxidation experiments in the EUPHORE chamber ...
  • The reactions of N-methylformamide and N,N-dimethylformamide with OH and their photo-oxidation under atmospheric conditions: experimental and theoretical studies 
    Bunkan, Arne Joakim Coldevin; Hetzler, Jens; Mikoviny, Tomas; Wisthaler, Armin; Nielsen, Claus Jørgen; Olzmann, Matthias (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    The reactions of OH radicals with CH3NHCHO (N-methylformamide, MF) and (CH3)2NCHO (N,N-dimethylformamide, DMF) have been studied by experimental and computational methods. Rate coefficients were determined as a function ...
  • A theoretical and experimental study of atmospheric reactions of amines and their degradation products 
    Bunkan, Arne Joakim Coldevin (Doctoral thesis, 2015)
    Amine-based CO2 capture has been proposed as a way of mitigating climate change. In this work, the fundamental processes governing the atmospheric gas phase chemistry of amines released from CO2 capture have been studiedusing ...
