Vibrational frequency tunneling splitting

A major role is played by vibrations with frequencies 318cm and 1378cm . The tunneling splitting increases by several times as the quantum numbers of these vibrations increase. The... 

So far the effect of nonadditivity in water has been studied in the context of various structural properties, vibrationally averaged structures, O-H frequency shifts [89], zero-point energies, rotational constants, cluster predissociation dynamics and tunneling splittings [58],... 

Whenever the dependence r(T) is reconstructed, we can simulate it and fitting will give us the magnitudes of the potential barrier, To, the tunnelling splitting, rF, the vibrational frequency, vo, the deformation potential, b, and the energy of inevitable strain, mq. For a doubly degenerate states one can use the expressions (38)-(40). 

It is worthwhile to note that the charged Bose gas trapped in the double well potential Ua of Eq. 50 behaves as an inverted Josephson junction (N-S-S-N). The super-current, which accompanies the matter wave coherence, is induced between the degenerate resonance states of the adjacent wells at the frequency of the tunnel splitting A response time, as is typical of tunnel junctions (whose frequency cutoff is much smaller than the vibrational frequency even for nano junctions). The coherent oscillations of the Josephson current can be observed by virtue of their slow frequency A V which is robustly controlled by the bias voltage. 

In the paper of Madeja and Havenith the observation of 409 lines in the frequency range from 1241.7 to 1250.7 cm i was reported. All lines could be assigned to the C-O stretch vibrational band. The splitting due to proton transfer tunneling was fully resolved (see Fig. 2.3). The frequency range from 1241.6 to 1242.6 cm is displayed it can cdearly be seen that each rotational vibrational line is split into two fully resolved tunneling components.
