1 Ab initio CIS/6-311++G(d,p) calculations of geometry and vibrational frequencies have been carried out in the A state of tropolone. Tropolone suppressor of cytokine signaling 5 Homo sapiens
2 The model potential energy surfaces, based on the CIS/6-311++G(d,p) calculations, give good estimation of the tunneling energy splittings in the vibrationally ground and excited states of tropolone and explain monotonic decrease in tunneling splittings with the excitation of low-frequency out-of-plane modes and increase in the tunneling splittings with the excitation of low-frequency planar modes.
