Notes:
The tunneling dynamics of one- and two-dimensional cubic oscillators having randomly fluctuating harmonic force constants (Kt) are studied numerically by invoking the time-dependent Fourier grid Hamiltonian method. The influence of the frequency and strength of the fluctuation on the tunneling probability and tunneling rate is analyzed. The predicted nature of the influence depends upon whether the cubic oscillator is one- or two-dimensional. The possibility of mapping the proton-transfer systems onto the present model is explored. © 1997 John Wiley & Sons, Inc. Int J Quant Chem 64: 403-409, 1997
