Data availability

The data that support the findings of this study are available within the article and its supplementary material. A ZIP archive contains the PGOPHER project files (.pgo) for both rovibronic and vibronic analyses, the photodissociation spectrum of N2O+, and a TXT file with the list of vibronic transitions used as input for the global fit in PGOPHER. These files enable full reproduction of the simulations and global fitting procedures presented in this work.
