In the published manuscript, we studied the spin–lattice and spin–phonon interactions in monolayer CrI₃ by using density functional theory calculations. There were several mistakes in the mode symmetries in the original manuscript.

Specifically, the monolayer CrI₃ possesses a D_3d point group of symmetry and the irreducible representations of the phonon modes at Γ should be decomposed into Γ_D3d = 2A_1g + 2A_2g + A_1u + 3A_2u + 4E_g + 4E_u, instead of Γ_D3d = 2A_1g + 2A_2g + 2A_1u + 2A_2u + 4E_g + 4E_u, as in the manuscript (Section 3.3).

The acoustic modes are E_u + A_2u, i.e., the doubly degenerate E_u mode, and one A_2u mode, not E_u + A_1u. In addition, the A_2g mode at 217.6 cm⁻¹ is neither Raman active nor IR active, thus is a silent mode.

Finally, as shown in Fig. 4(j), the mode at 134.5 cm⁻¹ is an A_1u mode, while the mode at 264.7 cm⁻¹ (Fig. 4(n)) should be an A_2u mode.

The conclusions in the published manuscript are not affected by these corrections.

We are grateful to Liu et al.¹ who pointed out these mistakes in our manuscript.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
