Total photoproduct yield spectra of BNH⁺ measured atPIIM (solid purple) and at SOLEIL (dotted purple), obtained by summing all photoproducts. Theoretical absorption spectra of BNH⁺ (solid green line calculated by TD-DFT. The theoretical spectra are obtained by convoluting the stick spectra with Gaussian functions of 0.25 eV full width at half maximum and have been shifted by −0.4 eV. The final electronic excited states of the dominant electronic transitions for each band are labeled.
