Quantum yields of I(/sup 2/P/sub 1/2/) for CF/sub 3/I, C/sub 2/F/sub 5/I, i-C/sub 3/F/sub 7/I, n-C/sub 3/F/sub 7/I,n-C/sub 6/F/sub 13/I, and 1,2-C/sub 2/F/sub 4/I/sub 2/ at 308 and 248 nm

A new method is applied to measure the wavelength-resolved quantum yields of I(/sup 2/P/sub 1/2/) for six molecules relevant to the iodine I(/sup 2/P/sub 1/2/) atoms and accounts for the strong exciplex emission, also at 1.3 ..mu..m, from the I(/sup 2/P/sub 1/2/)--iodide molecules. In addition, digital processing is used to correct for noise, quenching, and the detector rise time. These features avoided the shortcomings of previous measurements. The following molecules were investigated: CF/sub 3/I, C/sub 2/F/sub 5/I, i-C/sub 3/F/sub 7/I, n-C/sub 3/F/sub 7/I, n-C/sub 6/F/sub 13/I, and 1,2-C/sub 2/F/sub 4/I/sub 2/. All six iodides present high yields of I(/sup 2/P/sub 1/2/) at the pumping wavelengths of 308 and 248 nm used. The high I(/sup 2/P/sub 1/2/) yields for the molecules n-C/sub 6/F/sub 13/I and 1,2-C/sub 2/F/sub 4/I/sub 2/ are reported for the first time.
