“…The time-resolved ITS spectroscopy provides the spectral information as well as decoherence of vibrational states with a femtosecond temporal resolution. The decoherence time of certain states is important and fundamental in many fields, such as alignment of molecules, , remote atmospheric lasing, , quantum lithography, , superradiance, − and quantum information . In principle, the ITS technique can be extended to study chemical reactions, molecular structure, environmental dynamics, phonon dynamics, and phonon–exciton coupling in low-dimensional materials.…”
