Effects of Symmetrical Substitution on Triplet Propynylidene

Dr. Eric V. Patterson, Faculty Mentor

Propynylidene and its derivatives are triplet diradicals with unusual molecular geometries. These geometries may fluctuate significantly on a short time scale. Atom-centered density matrix propagation (ADMP), a form of ab initio molecular dynamics, has been used to determine time-averaged geometries for propynylidene and a number of symmetrically substituted derivatives. Our results will lead to a better understanding of the molecular geometries and properties of these and other related interstellar organic molecules.
