Theoretical developments for precision spectroscopy of polyatomic and polyelectronic molecules

Project description

Probing quantum dynamics in small molecule systems

Exploring the quantum mechanical properties of small molecules provides the basis for a quantitative understanding of chemistry and also a testing ground for new theories of molecular structure and reactivity. The EU-funded POLYQUANT project aims to provide a quantum mechanical computation of the non-adiabatic, relativistic and radiative effects of small molecules. The collected data will provide fundamental information about the dynamical fingerprint of the molecular systems and will provide the basis for simulating a variety of molecular phenomena, including how molecules interact with ultra-fast lasers.

Objective

I propose research for an increasingly accurate quantum mechanical computation of small molecular systems including non-adiabatic, relativistic, and radiative effects. The computed rovibronic energy intervals will be directly comparable with high-resolution and precision spectroscopy measurements. The accuracy goal for theory (and experiment) is more than six-orders of magnitude tighter than the usual chemical accuracy defined to be on the order of 1 kcal/mol. The rovibronic eigenstates obtained from effective non-adiabatic, relativistic-radiative Hamiltonians to be developed will provide the most fundamental and most detailed quantum dynamical fingerprint of the molecular system, and as a complete database they are necessary for the simulation of a variety of molecular phenomena including ultrafast laser-molecule interactions.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
