AIMD as well as classical MD-based approaches provide an overall description of the modes activated at a specific temperature range. A large number of studies have been conducted on the computation of the vibrational spectra for various systems from dynamic approaches. The calculation of the vibrational spectrum of liquid water using classical MD and AIMD has been discussed in several studies, along with other liquid, gas-phase, and air-water interface systems. In the case of solids, the vibrational spectra of high-pressure ice, hydrogen chloride hydrates, crystalline naphthalene, crystalline paracetamol, zeolites, metal-halide perovskites and MOFs have so far been investigated via MD-based approaches. The application of such methods for predicting IR and Raman spectra of 2D materials has been scarce. We are aware of two recent Raman studies on 2D YbOCl and 2D titanium carbide MXene, the latter one in combination with machinelearned force-fields.
