This data set was used to examine the reactive dynamics and spectroscopic properties of three beta-diketones: malonaldehyde (MA, propandial), acetoacetaldehyde (AAA, 3- oxobutanal) and acetylacetone (AcAc, pentan-2,4-dion), in a neural network based manner. The data set contains different geometries for the three molecules as well as for substructures (Amons [1]). In total the data set contains 71208 geometries with reference energies, forces and dipole moments calculated at the MP2/aug-cc-pVTZ level of theory calculated using the MOLPRO 2018.2.0 [2].
