Highly Sensitive Ammonia Probes of a Variable Proton-to-Electron Mass Ratio
Original language description
The mass sensitivity of the vibration rotation inversion energy levels of ammonia is probed using the nonrigid inverter theory. It is shown that the sensitivity exhibits non-negligible centrifugal distortion dependence, which is currently disregarded. The centrifugal distortion effects are especially important in the case of the Delta k = +/-3 "forbidden" transitions involving accidentally coinciding ro-inversional states vertical bar a,J,K= 3 > and vertical bar s,J,K = 0) of the nu(2) vibrational stateof (NH3)-N-14. The energy differences of these states exhibit very anomalous mass sensitivities (see Jansen et al. J. Chem. Phys. 2014, 140, 010901), thus appearing as new highly sensitive probes of the cosmological variability of the proton-to-electronmass ratio.
