Size dependence of HF vibrational frequency shift for ArnHF (n=1–14) van der Waals clusters via quantum five-dimensional bound state calculations

HF vibrational frequency shifts for ArnHF (n=1–14) clusters have been determined for the first time using quantum 5D bound state calculations. Our results for n=1–4 clusters are in very good agreement with the available experimental data. The size dependence of the redshift is predicted to be very nonmonotonic.
