    • J. Chappuis, Ann. d. l''ecole Norm. Sup. 11, 159 (1882). The opening sentence of the paper states that Chappuis and M. Hautefeuille had obtained the experimental data during calendar year 1880. It is noteworthy that this is also the paper in which the famous Chappuis band system of ozone was first reported, so N O3 and O3 molecules that are certainly connected in the context of atmospheric chemistry were also connected in this famous paper. On pp. 137-138, Chappuis reports eight bands at 665-668, 639, 628-632, 625-628, 617, 606, 598, and 588.5-590 nm, and states that the first and fourth of these are les plus noires. Apart from a small calibration error of ∼1 nm, this is a perfect description of the N O3 band system, and indeed the first and fourth of these bands are the strongest. These bands were, however, not attributed to N O3 in this work. It is amusing to note that the second band at 639 nm is, in fact, the 410 101 hot band transition; so some information about the anomalously low value of ν4 and, hence, the strong vibronic coupling in the ground state was available almost a half century before the dawn of modern quantum mechanics.

    • E. Warburg and G. Leithäuser, Ann. Phys. 0003-3804 23, 209 (1907). These workers cite Chappuis for earlier observations and correct the aforementioned calibration error. The absorption spectrum of N O3 was evidently also recorded by E. Ladenburg and E. Lehmann, Ann. Phys. 21, 305 (1906). The positions reported by Warburg and Leithäuser are within a few angstroms of the correct positions.

    • The first reported vibrational frequency of N O3 was a weak feature between 1325 and 1375 cm-1 [F. Cramarossa and H. S. Johnston, J. Chem. Phys. 0021-9606 10.1063/1.1696797 43, 727 (1965)]. However subsequent work [R. A. Graham and H. S. Johnston, J. Phys. Chem. 82, 254 (1978)] revealed that N2 O5, rather than N O3, is the carrier of this feature.

    • The term "artifactual symmetry breaking" is used here in the sense outlined by Davidson and Borden [E. R. Davidson and W. T. Borden, J. Phys. Chem. 87, 3063 (1983)]. An advanced discussion of how the PJT effect manifests itself as both "artifactual" and "real" symmetry breaking in quantum chemistry is given in Refs..

Equation has also been called the "harmonic approximation" (to the so-called dynamical Born-Huang expansion, which allows the electronic wave function to vary with the nuclear coordinate) (Refs.), but this is perhaps unfortunate as it has nothing to do with the harmonic approximation to molecular vibrations, nor is it truly an approximation in principle.

    • It is not possible to determine the sign of the coupling constant by this treatment, but the relative signs of coupling constants can be inferred from the quadratic force field of the adiabatic surfaces. Specifically, the coupling constants λi and λj have the same sign if the corresponding off-diagonal force constant element is negative and positive for the lower and upper interacting states, respectively. They have different signs if the situation is reversed. However, analytic calculation of the coupling constants has recently been implemented in the EOMIP-CCSD approximation [J. F. Stanton and J. Gauss (to be published)] and confirms that the signs of λ3; X̃ B̃ and λ4; X̃ B̃ are those given in Table..
