✦ Synopsis
The coherent Raman spectra of electrically discharged 14 N 2 and 15 N 2 were analysed using the deformationally self-consistent procedure for the treatment of spectral data. By making use of eight independent unconstrained parameters, 356 measured spectral lines were reproduced with s = 0.0023 cm -1 , ŝ = 1.96 and F = 8.74 × 10 13 . From a marginally evaluated value of the parameter t N 0 , related to non-adiabatic rotational effects, we predicted a rough value of the rotational g-factor for 15 N 2 g 0 = -0.37( ), near the known experimental value g 0 = -0.2593(5). Fit with the constrained t N 0 yielded s = 0.0023 cm -1 , ŝ = 1.96, F = 1.00×10 14 , and the set of seven well evaluated parameters representing the Born-Oppenheimer potential energy function and non-adiabatic vibrational effects.
