N2 - The spectrum of triatomic molecules with close rovibrational opposite parity levels is sensitive to the P,T-odd effects. This makes them a convenient platform for the experimental search of a new physics. Among the promising candidates, one may distinguish YbOH as a non-radioactive compound with a heavy atom.
