Figure 6

Plot of the F wt.% versus 3,565/3,390 intensity ratio showing a strong correlation between peak height ratios (i.e., the spectra shape) and F concentration. The linear regression resulted in F (wt.%) = -0.36 + 2.3 R3,565/3,390 where r2 = 0.938. Small dots are the polarized spectra data, and large symbols are the unpolarized data with symbols corresponding to the key in Figure 1.
