Rotational line strengths for the CN $B{}^2{\Sigma }^{+}-X{}^2{\Sigma }^{+}$ (5,4) band

James O. Hornkohl, Christian G. Parigger

Rotational line strengths, computed from eigenvectors of Hund's case (a) matrix representations of the upper and lower Hamiltonians using Wigner-Witmer basis functions, show a larg…
