Raman-spectra of NOCl and Cl2 photodissociation dynamics

The resonance enhanced Raman spectra of NOCl and Cl2 were recorded at a range of laser wavelengths from 514nm to 355nm, in both static and flow cells. A progression of overtone transitions (up to ν′′ = 13) was observed in the Raman spectrum of Cl2 at 355nm. NO overtones were observed for the NOCl dissociation at any of the wavelengths investigated. This suggests that the NOCl photodissociation may not be as fast as was previously thought.
