Abstract
Photolysis of CF2ClNO at 147 and 123 nm results in electronically excited fragments, fluorescence from which is observed. At 147 nm NO (B2Π) is produced, giving rise to the well known NO β-bands, contrasting with previous studies on CF3NO, in which NO (A2∑+) dominated. Addition of non-reactive gases (e.g., He) results in quenching of fluorescence from the higher vibronic levels of the NO (B2Π) state, while at the same time fluorescence from NO(A2∑+) becomes increasingly important. Photolysis at 123 nm give a very different emission spectrum, the most important contributor being the (1B1) state of CF2. Ionization also occurs at 123 nm (10.03 eV) with a quantum yield of ca. 0.08. These results are compared and contrasted with data obtained previously for CF3NO.
