โฆ Synopsis
A novel emission spectrum extending from 5500 to 8600 A has been observed during the gas-phase reaction of F2 with CS2. Long progressions in the lower-state (presumably the ground-state) bending frequency and shorter progressions in a ground-state stretching frequency were observed. A partial vibrational analysis is reported, from which two new frequencies are obtained: v; = 356 + 5 and v: = 83 1 k 8 cm-'.The electronic origin lies near 18500f 1200 cm-'. The spectrum is tentatively assigned to the FCS radical.
