Abstract

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 (CH$_{3}$NC, NCS, H$_{2}$CS, HCN and HNC) were identified via their pure rotational spectra. Observation of CH$_{3}$NC and NCS are consistent with previous studies of this system, however it is the first detection of H$_{2}$CS and HCN/HNC. Branching ratios were obtained from these data and will be discussed.
