    • Although Z. Shuai and J. L. Brédas, Phys. Rev B 46, 4395 (1992) claim that the VEH treatment of polyacetylene yields results similar to ab initio, a glance at their Table II shows substantial deviation, particularly at long chain lengths.

    • In a paper soon to be submitted it will be shown that the PPP method [see Z. G. Soos and P. C. McWilliams, J. Chem. Phys. 95, 2127(1991)] leads to a completely wrong prediction of the effect of interchain interactions on the hyperpolarizability of linear polyenes.

    • This cut-off parameter was determined by inspection. It is substantially larger than the maximum difference between any two consecutive values in the stable region.

    • The factor 1/10 is the same as that used previously by KTRH. For the most part extrapolations eliminated by this criterion are also eliminated by the maximum allowable oscillation criterion.

    • Of course, the optimized geometry of all oligomers to be considered in a subsequent vibrational distortion FOM study would still be required.
