Notes

1Lowest observed level and ΔG, vibrational numbering unknown. The observed transitions are v-3 at 23327 cm-1, v-4 and (v+1)-4.
2One level only. Vibrational numbering uncertain; the authors in Antic-Jovanovic, Pesic, et al., 1968 suggest v=1. Perturbations.
3These are values of ΔG(3/2),B1, r1,v(1-0). v=0 not observed.
4Spin doubling Δν12(v=0) = +0.1674N(N+1) + ...; Δν12(v=1)= +0.1743N(N+1) + ....
5G «rarrw» X1 is considerably weaker than G → X2. Relative branch intensities in both sub-bands are unusual.
6N'=0 relative to {J"=0}.
7A0 = -6.24, A1 = -31.87. Also J-dependent terms Appelblad and Lagerqvist, 1974, 2.
8v=0 perturbed. Λ-type doubling in v=1. For 2Π1/2, Δνfe = (-)[0.3190(J+1/2) - ...]; For 2Π3/2,Δνfe = (-)[2.74E-5(J-1/2)(J+1/2)(J+3/2) - ...].
9J'=1/2 relative to J"= 1/2 (average of {F1} and F2).
10v=0 strongly perturbed.
11Spin-doubling constants γ0 = -0.1952, γ1 = -0.1908.
12A0 = -276.11, A1 = -272.28, A2 = -268.69; also J-dependent terms Appelblad and Lagerqvist, 1974, 2.
13Λ-type doubling , Δνfe(2Π1/2) = (-)[0.0148(J+1/2) - ...](average of v=0,1,2).
14The absence of an ESR spectrum attributable to matrix isolated CuO is compatible with a 2Π ground state Thompson, Easley, et al., 1973.
