A new method generates high-level CCSD(T) accuracy in potential energy surfaces, improving accuracy with limited data points.

The method significantly reduces RMSE in potential energy surfaces from 829.2 to 56.0 cm-1 using just 272 reference data points.
Comparative analysis shows the approach achieves CCSD(T)-quality data while maintaining costs similar to standard DFT methods.
Application to molecules like HFCO and uracil illustrates the efficiency and effectiveness in predicting energies on potential energy surfaces.
The ACP-augmented protocol can enhance vibrational frequencies for computational quantum dynamics and spectroscopic studies.

Nazemi-Ashani et al. (2025) studied this question.
