Knowing the energy of light absorbed by a molecule enables us to understand its structure, its quantum states, its interaction with other molecules and its potential technological applications. Molecules with a high probability of simultaneously absorbing two low-energy photons of light have a wide range of applications: as molecular probes in high-resolution microscopy, as substrates for data storage in dense three-dimensional structures or as vectors in medicinal treatments.

However, studying the phenomenon by direct experimental means presents difficulties. This is why computer simulations are being carried out to complement the spectroscopic characterisation. Additionally, simulations offer a microscopic view that is difficult to access in experiments. ...
