Analysis of the IRPD spectrum of the BZH~+ monomer is consistent with the presence of the cis and trans isomers of the oxonium ions, which is confirmed by the cluster spectra. No signature of the less stable carbenium ions is detected. Frequency shifts in the IRPD spectra of dimers and ...

The spectrum of DH3 at 1 min is very similar to that of DH1 at 8 min indicating the acceleration of the hydrolysis rate in presence of H2O. The interaction between the freshly produced MeOH and DAMO might be the responsible of the band shift to higher wavenumbers at low reaction time. ...
