Twisting two vertically stacked layers of TMDCs introduces an additional degree of freedom that can tune their physical properties. In this work, we investigate the interlayer coupling of twisted 2L TMDCs using excitation-energy dependent Raman spectroscopy with laser excitation near the C-exciton resonance.
