1. Kern-Michler, D. et al. Controlling photochemistry via isotopomers and IR pre-excitation. J. Am. Chem. Soc. 140, 926–931 (2018). This paper describes the VIPER technique and its use as a means to achieve selective excitation of specific isotopomers.
2. Delor, M. et al. Directing the path of light-induced electron transfer at a molecular fork using vibrational excitation. Nat. Chem. 9, 1099–1104 (2017). This paper presents a demonstration of the principle of optical control by using molecular vibrations to direct the motion of electrons in a molecule.

Lett. 10, 1967–1972 (2019). This paper shows how photoluminescence detection can be used to monitor vibronic effects in a model small-molecule system.
4. Kim, H. et al. Direct observation of mode-specific phonon-band gap coupling in methylammonium lead halide perovskites. Nat. Commun. 8, 687 (2017). This paper reports a demonstration of vibrational control in a perovskite material; the modes of the perovskite’s inorganic lattice were used to induce transient changes in the bandgap of the perovskite.
5. Dong, W. et al. Surface passivation and energetic modification suppress nonradiative recombination in perovskite solar cells. Nano-Micro Lett. 14, 108 (2022). This paper describes how compositional engineering of perovskites can be used to inhibit cation rotation to suppress non-radiative losses.
