Overview

Randomized trial shows alternative fragmentation paths in formaldehyde, suggesting new dynamics.

Key Points

  • This research aims to investigate the dynamics of formaldehyde fragmentation through photolysis.
  • Measured CO(v,J) distributions from photolysis of H2CO and D2CO across various bands.
  • Analyzed the populations of CO fragments in low and high rotational states.
  • Proposed two models explaining the dynamics of dissociation.
  • A significant fraction of CO(v=0) is in low rotational states (JCO<15) when excitation is above the H+HCO dissociation threshold.
  • No measurable low-JCO states are found when photolyzed on the 2141 band, which lies below the threshold.
  • New dissociation paths are suggested, possibly involving a second fragmentation route.
