Fluorescence spectroscopy of supersonically cooled CFCI

Abstract

The spectra of the cold chlorofluorocarbene, CFCI, were generated using a technique combinining d.c. discharge with pulsed supersonic expansion and with laser-induced fluorescence detection of the products. The fluorescence excitation spectra were recorded using a pulsed, tunable dye laser and were analysed. Information about the structure was obtained by comparing the experimental rotational contours with the simulated band profiles. The obtained spectroscopic constants and structural parameters are summarized and compared with the previously available data and with the theoretical predictions.
