# Water TD-DFT example

`tddft-water.qvf` is the `tddft.qvf` reference archive of the qvf
conformance corpus at release v0.5.0, copied unchanged. It holds a water
ground-state wavefunction, an `excited_states` section with three singlet
states (B1, A2, A1), the hole and particle natural transition orbitals of
state 1, its transition density and a UV-Vis spectrum. The walkthrough's
"Excited states and natural transition orbitals" section opens it.
