Trimethylamine (TMA) is a tertiary aliphatic amine that stands as a potential marker for life beyond Earth due to only being naturally produced via biotic means. However, its propensity to undergo photodissociation in the gas phase when excited by a deep ultraviolet photon means that its amine daughter product could serve as an additional biomarker and confirmational spectral signature of TMA in exoplanetary atmospheres…

Delayed photoisomerisation of the trans-PSB3 retinal toy model using on-the-fly quantum dynamics

Delayed photoisomerisation of the trans-PSB3 retinal toy model using on-the-fly quantum dynamics

We explore the trans–cis photoisomerisation process in a representative retinal protonated Schiff base known as trans-PSB3, employing the quantum dynamics method direct dynamics variational multiconfigurational Gaussian -DD-vMCG- in full dimensionality, i.e., 36 degrees of freedom on potential energy surfaces computed on-the-fly using the SA(2)-CAS(6,6)SCF electronic structure method with the 6-31G basis set…
