Photodissociation of Methyl Isothiocyanate Studied Using Chirped Pulse Uniform Flow Spectroscopy
Résumé
Chirped-Pulse Fourier-transform microwave spectroscopy has been applied in a uniform supersonic flow (Chirped-pulse/Uniform flow, CPUF) to study the 193 nm photodissociation of methyl isothiocyanate (MITC). Several products (CH3NC, NCS, H2CS, HCN and HNC) were identified via their pure rotational spectra. Observation of CH3NC and NCS are consistent with previous studies of this system, however it is the first detection of H2CS and HCN/HNC. Branching ratios were obtained from these data and will be discussed.
