PROSPECTS FOR FUNDAMENTAL SYMMETRY TESTS WITH POLYATOMIC MOLECULES

Abstract

Special features of polyatomic molecules make them attractive candidates for search for violation of fundamental symmetries and variation of fundamental constants [1, 2]. We discuss the possibility of searching for nuclear spin-dependent space-parity violating ($al NSD-PV$) interaction in closed-shell and open-shell polyatomic molecules. The parameter $W_{\mathrm a}$ of the effective molecular spin-rotational Hamiltonian characterising the strength of $al NSD-PV$~ interaction in open-shell linear molecules is discussed and approaches for its calculation outlined. In addition, possibilities for detecting $al NSD-PV$~ in chiral molecules via NMR and MW spectroscopy are presented. \\~ REFERENCES: \\begin{enumerate} \item C. Stoeffler et al, Phys. Chem. Chem.
