Abstract:We previously presented the least-squares fit of the benzonitrile (\chem{C_6H_5CN}, C$_{2v}$, $\mu$$_{a}$ = 4.5 D) ground vibrational state, which was fit to a partial octic Hamiltonian, as well as the first analysis of its two Coriolis-coupled, lowest-energy fundamental states, \nub{22} and \nub{33}.$^{1}$ Herein, we present the continuation of this work: the analysis and fitting of the Coriolis- and Fermi-coupled triad of the overtone and combination states (\nub{22} = 2, \nub{33} = 2, and \nub{22} + \nub{33}) near 315 \wn. Approximately 3000 transitions are assigned for each state, including multiple resonances, and their least-squares fitting results in precise energy separations that are in agreement with those expected based on the energy separation determined for \nub{22} and \nub{33}. $\\$ $\\$ 1.
