Comparative study of CCSD(T) and DFT methods: Electronic (hyper)polarizabilities of glycine

► We computed dipole moments and static electronic (hyper)polarizabilities of the lowest-energy conformations of glycine. ► We compared high-level correlated ab initio with traditional and long-range corrected DFT methods. ► Dipole moment and first-order hyperpolarizability are potentially useful to distinguish glycine conformations.
