WebInclusion of the Duschinsky effect in the Herzberg-Teller theory for two or more nontotally symmetric perturbing vibrations introduces a constructive-destructive interference problem, involving the "forbidden" transition moments similar to the one that arises in the theory of Craig and Small on totally symmetric vibrational perturbations. WebFeb 28, 2024 · In the bottom panels, the effect of the Duschinsky rotation is dissected by considering the minimal scenario of a single mode (1147 cm − 1), coupled to a nondisplaced low-frequency mode (80 cm − 1) and detected on a “spectator” mode (822 cm − 1).
WebJul 26, 2024 · The computationally efficient approach by Tapavicza et al. requires information of optimized ground and excited state structures as well as their harmonic frequencies as input data. The approach does not take temperature effects into account, but it allows Duschinsky mixing of all vibrational modes. 4
