Fig. 1: Infrared absorbance of CrSBr.
From: Pressure-induced structural phase transitions in CrSBr
Synchrotron infrared spectrum of CrSBr at ambient conditions and the theoretically calculated mode displacement patterns. Blue, yellow, and red represent chromium, sulfur, and bromine atoms, respectively. The inset shows a close-up view of the weak 1B2u phonon with its displacement pattern. The positions of the 2B3u, 2B2u, and 2B1u modes were determined using traditional oscillator fitting techniques as discussed in the text.
