How accurate are approximate methods for evaluating partition functions for hindered internal rotations?

Lin, Ching-Yeh; Izgorodina, Ekaterina; Coote, Michelle


The accuracy of several low-cost methods (harmonic oscillator approximation, CT-Cω, SR-TDPPI-HS, and TDPPI-HS) for calculating one-dimensional hindered rotor (1D-HR) partition functions is assessed for a test set of 644 rotations in 104 organic molecules
