✦ Synopsis

Eigenstates of the rotational states N=O and N= 1 of the S, ( 'BsU) vibrational ground state of pyraxine interacting with background triplet states have heen investigated by quantum beat spectroscopy. Mixing of triplet states with different total angular momenta J, excluding nuclear spin, has been established by analysis of sub-natural linewidth quantum bent spectra. Anisotropic quantum beats provide an estimate of the eigenstate hype&e splittings. Consequences of these observations on the interpretation of previously recorded high-resolution spectra are discussed.

An external modulated cw narrow band laser and a collimated molecular beam was used to apply high-resolution quantum beat spectroscopy to the molecular eigenstate spectrum of pyrazine. A resolution of 1 MHz was achieved in the near ultraviolet region. A beat pattern was observed from the temporal de
