The experimental photodetachment spectra of Al$_6$N at 193 nm \footnote{

for the first seven low-lying electronic states, are interpreted theoretically using the vibronic coupling theory. Here, the potential energy curves (PECs)
obtained through ab initio electronic structure calculations
provide the Hamiltonian parameters corresponding to the model vibronic Hamiltonian\footnote{
\href{https://doi.org/10.1016/0301-0104(78)87081-5}{doi:10.1016/0301-0104(78)87081-5},
L. S. Cederbaum , W. Domcke and H. Ko\"ppel, \textit{Chem. Phys.},
\textbf{44}, 319-326, (1978).} . These PECs also ascertained the
presence of non-adiabaticity among closely spaced electronic
states. Furthermore, the theoretical spectra were obtained utilising the time dependent and time-indipendent quantum chemistry approaches by
following uncoupled and coupled dynamics. In the uncoupled
dynamics, the vibrational structures of all spectral bands are
examined and discussed through Poisson intensity distribution
and wave packet density plots. At the same time, in the coupled
dynamics, we studied the nonadiabatic effects through reduced
dimensional calculations and diabatic electronic population
transfer.
