		in Chlorofluoroacetylene
	Guarnieri and Andolfatto [1] measured the chlorine nqcc's in FCCCl, and calculated an effective structure as a function of assumed CC bond length. The nqcc's calculated on these several structures are compared with the experimental values in Table 1.
	Table 1. Chlorine nqcc's in FCCCl (Xzz / MHz).     r(CC) Calc. Expt. [1]     35Cl 1.200 - 82.82 - 83.0(1)   1.203 - 82.62   1.206 - 82.54 1.209 - 82.45   37Cl 1.200 - 65.27 - 65.6(1)   1.203 - 65.12 1.206 - 65.05 1.209 - 64.98

	If CC = 1.200 Å, then FC = 1.278 Å and CCl = 1.636 Å.
	If CC = 1.203 Å, then FC = 1.276 Å and CCl = 1.634 Å.
	If CC = 1.206 Å, then FC = 1.274 Å and CCl = 1.633 Å.
	If CC = 1.209 Å, then FC = 1.270 Å and CCl = 1.632 Å.
