    • During the course of this study, we discovered that we had previously neglected to normalize the absorption spectrum derivatives to the light frequency. This omission in the earlier work accounts for the discrepancy between eq 1 in ref 13 and in this paper, and for the differences between the values reported for ATR in glued PMMA in both sources. The effect on Aa and |Δμ| is small (<10% and <20%, respectively) and the trends we have observed are not affected by this oversight.

    • Although most commencal low-density polyethylene at room temperature contains both amorphous and crystalline regions, recent fluorescence studies on tethered pyrene molecules (Zimmerman, O. E.; Weiss, R. G. J. Phys. Chem. A 1998,102, 5364-5374) indicate that probe molecules inhabit the amorphous or interfacial (between crystalline and amorphous) regions of the film.

    • One could argue at this point that the effects we observe in ATR are simply the result of isomerizations of the molecule. However, calculations of both Δμ and Δα performed on 13- and 9-ro-retinal differ from that of ATR by only 15%. This small deviation would hardly account for the large variations seen here. Also, ATR is the most stable isomer. In solutions of ATR irradiated for 2 h in hexane at 430 nm, ATR formed at least 60% of the mixture at equilibrium (Waddell, W. H.; Hopkins, D. L. J. Am. Chem. Soc. 1977, 99, 6457-6459).
